Expected Behavior

Not to crash with a Problem Report when invoking various functions not from the UI (Streamdeck/Websocket being not from the UI)

Including but not limited to:

Current Behavior

Crashes with a problem report

Steps to Reproduce

Method 1:

  1. Using the streamdeck and it's plugin switch between profiles a number of times (it's not directly tied to speed of switching aka spamming switching), not sure what mechanism is used under the hood there.

Method 2:

  1. Using the websocket switch between profiles a number of times

Method 3:

  1. Using the websocket under the currently selected profle
  2. Call GetProfileList
  3. Then it crashes

Some of these methods are inconsistent/not 100% reliable to trigger, but I also did a full nuke of OBS from my mac and did a fresh grab of latest release and same issue presents: IE no extra plugins installed beyond activating the WebSocket.

Sometimes Mac OBS will also crash the moment I connect a websocket. At identify I'll call "GetProfileList" as the first call.

In the last round of testing I have no sources in the only source collection either.

It also behaves similar on the RC1 of 30.2.0 And I have a report that it occurs on another users machine with release and OBS Blade (a seperate controller), granted blade also uses the websocket socket, it just rules out my code being at fault)

Doing the same "dumb shit" (if you pardon the expression) on windows cannot replicate the fault, so it seems localised to the mac version of OBS

Anything else we should know?

Mac Problem report for OBS Studio, The problem report is longer than 65536 chats so I've uploaded it to my pastebin https://pastebin.com/PFB1Rqmy

A second problem report https://pastebin.com/gzZRBmVc It's OBS Log file https://obsproject.com/logs/kAjQ3olT5TOkyNmY After doing a few profile changes via a WebSocket control

Yes it's a not normal aspect ratio here but I can cause the problem from just switching between a bunch of normal aspect ratio profiles, the profile I'm working with primarilly is for a vertical streaming platform, but I don't think that matters here

Same crash in both reports, putting it here to save someone a few seconds later:

I wonder if it relates to #10532 since the hiccup occurs around Getting Current Profiles and profiles/scenes share a similar fault. (found this when looking for a different bug)
