i even made a build from an older version of rpi-imager that i had modified, here is the boot files: https://cdn.oxmc-servers.online/uploads/my-embedded-build.zip

Closing, after cleaning and re-installing my os it worked, looks like it was my systems fault

Did you change any build settings?

As we also encountered problems after upgrading to a newer Mesa3D version for Pi 5, that it would crash if compiled optimized as size, while it did work optimized for speed (-O2).
There may be a timing specific bug out there...

Unsure if it was just a weird Linux issue or what, I'll try building the rpi-imager again from a clean slate

[oxmc]

This seems t be happening more and more often, im going to re-open the issue
