Hello and welcome.

That could be a software issue, but normally it is a hardware failure related issue.

I suggest running Apple Diagnostics and see if that reports anything like "machine check" in the report.

Also, do you have a current Time Machine or other backup of your data?

Hello sir, thanks for replying.

firstly, I wanted to give an update as my MacBook managed to boot correctly working perfectly fine but as soon as I restarted it went on the same loop.
As suggested, I tried to run Apple diagnostics but it shows no errors as it says that the device works fine.
The webcam doesn't work ( hardware problem ), could the two be related?

Finally , to respond to your last question, I don't have a back up to my data.

Appreciate your time for helping,

Geralt

Hello,

If the iSight camera isn't working it could be a hardware/software issue, and it could be related. Because Apple Diagnositcs didn't find anything, it could also be a corrupted macOS install.

I highly recommend starting up in safe mode and connecting an external drive to get a Time Machine or other backup of your data done, as this may require a reinstall/erase & install of macOS.

Hello,

I managed to erase and intstall macOS (Monterey) as suggested but after a week of performing very well the problem showed up again. Any idea what might be the issue?

thank you for your time,

Geralt
