Sorry this is my first time trying to report an issue via Github so I hope I did it correctly

[maillota]

I hit the same thing when upgrading nvidia drivers to 566.14 - it turned out that the driver didn't install properly after rebooting. I fixed it by reinstalling 566.14.

Device manager for my GPU had the following status message:
A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)

Did you actually try to stream, or just instinctively restarted sunshine due to the warnings in the UI?

[MNarath1]

Same issue here trough it usually works after a reboot again for a while trough in my case i am on fedora 41 KDE with a Nvidia rtx 2070 Super also using the prerelease version

there was just another nvidia driver update and when I checked sunshine post reboot it did not show an error this time.
Nvidia driver version is now 566.14 so I will keep an eye on it

Edit- I was on 566.14 but nvidia had another 566.14 so perhaps a dodgy install has caused this

Yeah the reboot fixes it but If I am not planning on gaming with moonlight and forget to sign in and check moonlight on my host it is a sad time when I go to game and dont have access to my host for a force reboot of sunshine

I have this issue on NixOS running plasma 6 wayland with an nvidia GeForce GTX 980. Rebooting does not help

Still get this error on the last pre-release, work well after restart. Drivers installed normally. Gtx 1080.

Restart of what, the target machine? The host machine? The Sunshine service?
