Fedora 38 system with Wayland and GeForce RTX 3060 crash a few min after startup

This desktop used to work, I don’t recall changing anything but Gnome Shell started crashing and now it is crashing a few min after start up. I could see “GPU has fallen off the bus” message in the logs, the GPU is only used by gnome-shell at this point as far as I can see, fans on the card are working.

kernel: 6.4.15-200.fc38.x86_64
nvidia version: 535.113.01

I am attaching the logs, could you tell what could be the issue ?

I opened the case, had a look at the GPU, restart the workstation, it did not crash …
Midas touch ? Were there something touching another thing that could have cause this ?
If you have any idea what could have been wrong, please let me know.

I thought my box was good but it had the issue again today …
I am sharing this new log:
