Temporary Launch Failures - quattro - 2025-08-20
A month or two ago, my Jellyfin instance started acting up. More often than not, it would fail to start during the period when all other applications in Windows start up (after booting into the system). However, if the prompted to start via the tray application, Jellyfin starts up with no issues. I've tried to look at the logs myself, but to no avail. Can someone else see something that I haven't?
For some bizarre reason uploading the log files would not result in anything happening, so I'll include them via pastebin.
System Details:
- Windows 11 Pro
- Jellyfin 10.10.7 (server installed on Windows)
- I can provide other details if necessary

Remove the C:\WINDOWS\system32' path for ffmpeg that is set in your user/system environmental variables in Windows.
To do so, type environmental in the Start menu and select "Edit environmental variables ..."
Then edit the path variable for both the user and the system variables, and remove the ffmpeg reference. Then you would need to restart the computer for the changes to take effect.

The interesting thing is that I don't have any environmental variables set for ffmpeg.
The one thing I do see pointing to system32 is the PSModulePath variable. Perhaps that's what's causing the error? It's still confusing because using "Start Jellyfin" via the tray app launches the application without any issues (usually).

You need to select "Path", then edit, and it will be in that menu.

Here's what the menu shows for Path (user variables):
I can't edit system variables for some reason.
RE: Temporary Launch Failures - theguymadmax - 2025-08-21
Type SystemPropertiesAdvanced in the start menu, select the entry that comes up, then click on Environmental Variables. You'll be able to edit the system environment variables from there. Delete the ffmpeg path in the user variables from your screenshot, and do so if it's also in the system variables.
RE: Temporary Launch Failures - quattro - 2025-08-21
Thank you for the detailed instructions. I've removed the ffmpeg path from the user variables, and am now looking at the system variables; just to make sure that I don't mess anything up, should I remove the %SystemRoot%/system32 path? (should I also remove %SystemRoot%?) I don't see a path for ffmpeg in the system variables so that doesn't have to be taken care of.
RE: Temporary Launch Failures - theguymadmax - 2025-08-21
Nothing to delete there. So just restart after deleting the ffmpeg path from the user variables.

Alright, thank you so much. I'll observe the behavior of Jellyfin for a couple of days and report back. By the way, I may have started noticing similar "access denied" issues across my other applications. Would you have any idea regarding whether there may be a bigger problem instead of just improperly defined paths?
