Bug Report OBS crashes on 'stop preview', not able to retrieve crash dumps

[kalstras]

OBS freezes after I click "stop preview", and when I force close it through "Not responding -> Close program", that appears after a bit of click at OBS window some time after it has been frozen, it does not generate any crash dumb or something like that - \AppData\Roaming\OBS\crashDumps is empty.

QSV is known to freeze. Use x264 if possible.

 

[kalstras]

Just tried, same with x264, no crash dump to salvage.

[R1CH]

Have you tried waiting for a full minute or two before killing OBS? It can take a while for various buffers to empty.

 

[kalstras]

Not then, but I tried that after you posted this, left it for 15 minutes. All the same, no crash dump.

[R1CH]

Next time it happens, right click OBS.exe in task manager and choose 'Create dump file' to create a manual crash dump.

 

[kalstras]

I did restart PC and it no longer happens. In case it does I will create manual crash dump as you have said.
