My Left and Right audio channels are swapped (and ONLY in Premiere)

[mr.shenanigans]

OK, so this is a post about Premiere's audio output, NOT about individual clips or timelines outputting incorrectly. 

For some reason, Premiere (22.1.2) swaps my headphone's left and right channels, but no other program does this. I'm on Windows 10.

I haven't found anyone else with this issue and of course searching the web returns a million results for how to change the channels on a particular clip.

Any recomenndations? The last thing I haven't tried is uninstalling and reinstalling, but trying not to do that in middle of project delivery.

If that doesn't work, try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn't work, try creating a new project and import the old one into it.
