Computer restarted because of a problem every time I startup computer

Hi all, I have an Imac 21,5" 2017, Intel core i5, Radeon Pro 555 2GB, 16GB DDR4 and Ventura 13.7.1


Since a few weeks I have this problem: I alway leave my Mac on and when opening in the morning it has a black screen and it does not respond to anything. After holding the on button for 10 sec and then starting again, it sometimes tries to startup and then hangs halfway.


When completely shutting down and removing power it will start up mostly. When logged in I alway have the message "computer restarted because of a problem". I have captured some messages:





I have tried restarting from recovery, reset SMC and did a reinstall of MacOS. No solution.


Do you have any idea what the problem is and what to do?

Seems to be related to the GPU, but hard to say if it is hardware or software. I'm leaning towards a hardware issue only due to the first screenshot showing the failure was due to "setPowerState", but this is not necessarily definitive. The other two screenshots show a different failure that is still related to the GPU. We may know more once you post an EtreCheck report as suggested by @Luis.


You can also try running the Apple Diagnostics to see if any hardware issues are detected. Unfortunately only a failing diagnostic result is useful, but that doesn't happen very often.
