Verbatim, two messages in the same minute:
"and now my nvidia app isnt working"
"and anything cant be done on fullscreen"
What happened next: the owner replied "U have to reinstall Nvidia app". The user did — "i did but still ccant run". The next morning he wrote "sry bro mb ifixed it" / "but pc fixed". So it resolved on his side, the cause was never established, and it was never ticketed until now.
That a reinstall did not fix it is the useful detail: a broken NVIDIA install would have been repaired by reinstalling. Something outside the app was keeping it from running.
A likely cause was found — and has been fixed
An audit this week found that the process-reduction step could stop NVIDIA's background service — the component the NVIDIA app and Control Panel talk to. With that service down, the NVIDIA app opens and does nothing, and a reinstall does not help, which matches this report exactly.
There was a protection list meant to prevent precisely this, but it was only consulted at a couple of call sites instead of inside the code that actually stops things — so it was being bypassed. It has been made canonical and is now enforced in every stop/kill path, which is the same fix that closed two other never-kill gaps found in the same pass.
This is a plausible cause, not a proven one. Nobody reproduced this user's machine, and the fullscreen half is not explained with the same confidence — a display/scaling backend being unavailable is a reasonable explanation for both symptoms at once, but it has not been demonstrated.
What would settle it
- @UnknownX4T: please retest on the next build and say whether the NVIDIA app still stops working after an optimize.
- If it happens again, the useful information is: which level was run (Safe / Aggressive / MAX / MAX+Risky), whether the NVIDIA app was open at the time, and whether a reboot brought it back (it should, if a stopped service is the cause).
Honest status
Cause identified as likely and fixed; not confirmed against this report. Keeping this open until someone retests, because closing it on a code fix we never validated against the symptom is how it comes back.
