[Windows 11] OBS crashes during regular Windows shutdown

Duplicate of #10833?

Btw I just tested it here and I didn't even had to stream to YT, just shutdown Windows 11 with OBS still open.
Then, when the PC restarted, I open OBS again, but received this dialog: (it is in portuguese BR)

"Safe Mode
OBS Studio did not shut down properly last session.
Would you like to start in safe mode (third-party plugins, scripts, and websockets disabled)?
Run in safe mode / Run in normal mode"

Possibly, there's not a lot of information in 10833 on what is causing it. Might be related, might not.

[Andre-Satorres]

I think it is related to this logic:
On obs-app main, a sentinel file is created. But it is deleted only if the function run_program() ends, which I believe might only happen if the window is closed (on click)

Then, next time application is started, the sentinel file already exists, and unclean_shutdown is set to TRUE, and trigger the message present in the log, and also in the #10833 title.

We should get a product decision: if this message is annoying and we want to get rid of it, let's think on a different approach rather than this sentinel file.

I believe we should put this "delete_safe_mode_sentinel" as required action on application closure

In the case of this issue (#10848), it was not merely a spurious an error dialog upon subsequent application launch (perhaps a false positive), but a genuine application crash (with an error dialog (invalid instruction executed) and a crash report) during the Windows shutdown process. In particular, an invalid instruction was executed thereby invoking a signal handler. See the attached crash report.
