OBS 31.1.1 recording failure

[Bobw111]

Just installed OBS 31.1.1 today, just before beginning my weekly session with a buddy in Arizona. Started recording, OBS showed recording during 2+ hour long session. Ended recording. OBS is set to automatically remux recording once recording is ended. Waited 5 minutes, but remux never began. Used Task Manager to end remux app, closed OBS, reopened OBS, and tried to remux recording. Remux ended almost instantly saying nothing to remux. I checked and the .mkv file that should have been recorded showed zero length. System is Windows 11 on a DELL Precision 3680 i7-14700 2.1GHz, 64GB ram, NVIDIA RTX 200 Ada w/16GB, drive recording stores to is 8TB with 3.84TB free space. I've previously had issues with OBS not stopping recording, or not remuxing, but can't figure out why. Only thing I have noticed is that Windows 11 might be putting hard drives into sleep mode since Windows explorer doesn't instantly open a drive like it used to on my old system with Windows 10. Any ideas would be greatly appreciate.

the file path sticks out to me

H:/#          OBS Recordings/2025-07-13 12-52-07.mkv

The path has worked fine in the past with prior versions. I'll knock out the spaces between # and OBS to see if that helps though.

There is one more thing. Windows 11 updates keep setting my drives to power down after 1 minute. Drives me nuts because then it takes about a minute for the system to power back up and show me the drive content whenever I use Windows Explorer (which I use quite a lot.) I've reset windows to never power down the drive. Hope that works for today's session.

OK. Today I got a recording 80 minutes long, but when I hit "Stop recording" OBS just sat there saying "stopping recording." Usually it jumps right into remuxing. So, I had to kill OBS in the task manager. I then restarted OBS and recorded about another 61 minutes. This time when I stopped recording remux started up instantly. I then manually ran remux on the first file and the remux ran fine. So, I'm guessing the windows powering down the drive after 1 minute is what causes OBS to not record anything. However that still doesn't explain why "Stop recording" hangs and requires killing OBS in the task manager.
