You rebooted twice before creating the bug-report.log, so there’s no real info to get from it.
If you didn’t reboot again since then, you might get a helpful log running
sudo journalctl -b -2 --no-pager >journal.log
To attach files, hovering the mouse over an existing post of yours will reveal a paperclip icon.
For now, I fixed the issue again by manually removing the driver, booting with Nouveau, then looking for any traces left of any version of the NVidia driver and deleting them all (config files, orphaned packages etc.), then reinstalling the driver.
Once this happens again, I will make a new log and attach it here (thanks for pointing out the paperclip!).
