So at the end of the process I got an error message that said: “Your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up.” I get that message when it tries to boot up with the external drive. It is still able to boot up with the internal drive.

After the error trying to boot from external and booting normally from interal right after, I was given the option to report the instance to Apple for more details. This is what it said:

Does that give any indication why it won't boot from the external drive? Is there another way to check if my internal drive is the problem? Thanks

That is the system report after a kernel panic. In general, kernel task indicates overheating of the system and kernel task will limit CPU activity in order to protect the Mac. If you were given the option to report this to Apple, you should. You can use Feedback Assistant to do so, and it will collect all this information to include with your feedback, along with some description from you on the circumstances.
I don’t have the reference resources I had when I was an AppleCare service provider, but maybe Apple will be nice enough to reply to your feedback. But this points to a hardware problem especially if it happens a lot, especially with the slowdowns you are experiencing. My immediate move, if I were in your situation, is to reinstall the system. That is the reason why, when you get a hold of the system installer, you should keep a copy for this very purpose. You should look into what version of macOS your system will allow. You can check and download the installer using Terminal.
Ok thanks I submitted feedback to Apple. The kernel panic only occurs when I try and boot up using the Monterey I installed on my external usb drive. So I’m stuck at the moment, unable to run macOS from my external drive to see if the problem persists independently of my internal drive. Is it possible the software isn’t compatible with my usb drive, resulting in the kernel panic? It’s a Sandisk ultra flair usb 3.0 64GB flash drive.
Now it seems like my options are to either buy a different external drive to try and install/run macOS on and return it after, or buy a new internal drive and it’ll either fix it or I return it. You mentioned that running macOS on an external drive would be the easiest way to check if the problem is with the internal drive, but is there another way that wouldn’t require me buying something?

Try booting into Recovery (power up and immediately hold down command-R, and assuming you are connected to the internet). Your internal drive does not have to be functional, nor do you have to have an external drive connected. If fact, you can erase/reformat your internal drive with Disk Utility via Recovery. So try booting into Recovery. (It doesn’t need to be “internet” Recovery, command-option-R; a simple command-R should work.) You only opt for internet recovery when simple recovery does not work, and the former takes so much longer to connect.
If you successfully connected to Recovery, I recommend first formatting your internal drive by opening Disk Utility. Afterwards, you will be given the option to install macOS. It will pick the latest version that your Mac will run. I’m also assuming that you have a Time Machine (or other form of) backup to migrate into your new installation. If you don’t care about your previus data, and you have your iCloud account name and password, you can set up the new system just as you would with a brand new setup.
Keep in mind that Recovery does not need your internal drive, so unless there are other hardware or firmware issues with the Mac, you should be able to proceed.
I’m not sure why you’re suggesting I do that again, I already have done that to see if anything was better (unfortunately it wasn’t) after erasing the internal drive and installing a fresh Monterey with a new user.

This thread has been very long and I don’t remember making that suggestion. Anyway, if you are not able to erase your drive and reinstall the system from within Recovery, then it’s very likely that the problem is hardware related.
I suggest calling Apple to locate an AASP near you. They should have testing facilities to diagnose the problem… hopefully. I’ve never had a positive result from any of their third-party providers and I always end up going to an Apple Store instead, and during those times, I have had to walk them through the problems to convince them that there were indeed hardware problems.
I understand, thanks for your patience. My previous post was not clear, I was able to use recovery and erase my internal drive, install the latest os, and set up as a new user. And I was still experiencing the same problems with that fresh setup.
I have exactly the same issue with my 2015 MacBook Pro, running Monterey. All of a sudden it decides to run very, very slowly. Have opened it up, fans are clean. Have run diagnostics, no faults reported. Have tried reinstalling, no difference, all the time Kernel_task is running at 200%+ and crippling the laptop. Takes for ever to just login and do anything.
If you do get a solution please do post here.

Do you have or know anyone with an external ssd that you could install Monterey on, and boot up with it to see if the problem is still there? That’s the one troubleshooting part I haven’t been able to try.
I ended up leaving mine at an apple store for them to run tests on it. The Genius Bar guy suspects the logic board will need to be replaced, at a cost of $625, which I won’t be moving forward with if that’s the case. Still waiting to hear from them.
I’ll have a dig around, not sure if I have a spare external SSD. Will report back.
If it’s a hardware fault, then like you, I would say it will be uneconomic to repair.
My Genius Bar came to the conclusion that the logic board needs to be replaced. Unfortunate news, will be ending this thread now.
