Question / Help OBS 20.0.1 crashes on start macOS 10.13

[SeeCraig]

OBS 20.0.1 crashes on start macOS 10.13
Perhaps this is a bug but need confirmation.
Crash seems to be AVFoundation CoreMedia related.

Here's the crash thread but I'll attach full log as well

So even with crash log and apparent involvement of AVFoundation CoreMedia this issue is unique to me with no suggestions for a fix?

No one?

Afraid not. I am not using 10.13.

Did you try the latest version, 20.1?

Just tested the exact same crash pointing to AVFoundation.
I tried a Safe Boot and then booting again hoping is was something the OS could fix.

Given the crash points to AVFoundation it doesn't seem to be related to any third party conflicts.
No background tasks running that would grab AVFoundation. Basically nothing running at all when I try to open OBS.
No other apps are crashing.

I have another system on 10.12.6 which isn't crashing so I'm wondering if this is a 10.13 specific issue.

Logged into another user account on the same computer.
OBS started without issue.
This indicated to me that it was a user account specific settings issue.
Logged back into the problem user account.
Went to
~/Library/Application Support/obs-studio
and deleted the entire folder.
OBS started without issue.

Problem solved.

First update OBS. You're on version 18. Update to version 20.
It's not clear at all that you read the thread and tried my solution which peterjobo reposted.
When posting on a thread which has recommendations it would be useful if you listed what you've tried. That would allow us to offer additional steps instead of reposting what has already been posted.
