After an interaction with one of the OBS contributors, I decided to make this post as a fuck you. Also nobody else has figured this out yet?
You're going to need the QT6 fix, specifically the 6.3.1 fix.
Step 1: Obtain OBS 29, get the zip and extract it.
Step 2: Apply the QT6 fix, just copy and replace.
Step 3: Open obs.dll with CFF Explorer or a hex editor, the next few steps can be done with either CFF Explorer or a hex editor

Save
or
For a hex editor, search for the hex 49 73 57 6F 77 36 34 50 72 6F 63 65 73 73 32
Change 32 to 00
