Expected Behavior

Obs should not crash when attempting to record, even if the formatting string is malformed.

Current Behavior

If the formatting includes creating a folder with trailing spaces in its name, obs errors on the first attempt at recording, and crashes on the second.

Steps to Reproduce

1. Change filename formatting to include a folder with trailing spaces (for example %CCYY-%MM-%DD /%hh-%mm-%ss)
2. Press Start recording, get the error shown below.
3. Press Start recording again, crash.
   ...

Anything else we should know?

error in question :

The crash report and the log do not correspond exactly because whether or not a crash report is generated by the crash is unreliable

Start by reproducing the issue on Windows 11 with the formatting string %CCYY-%MM-%DD /%hh-%mm-%ss, then inspect the linked OBS log and crash report. Done means starting a recording with the malformed formatting produces neither an error nor a crash.
