Camera Inaccessible & stuck on "finding camera" since 0.27.2 with multiple webcams, rolling back Electron fixes it

[VisualK]

Hi. Thanks for your hard work on this great tool. I've had this problem for almost a year, on every version I've tried since 0.27.2, with the same results. I thought if I waited it might get fixed, but nobody else seems to be complaining about this specific problem. So I'm submitting an issue.

PROBLEM:

When I try to start mocap, 99% of the time it will get stuck on "finding camera" or the webcam light turns on but after a while it says "Camera Inaccessible". I've tried multiple webcams, same problem. It sometimes works once after a reboot (I think). Sometimes randomly without.

TESTING:

I unpack into a new folder when I use a new version of XR Animator, to make sure it's using the new files. I tried deleting AppData/Roaming/System Animator (Electron) and resetting settings (including deleting TEMP/_config_local), many, many times. It didn't solve the problem.

I checked DevTools Console Tab and the only red text said camera inaccessible and pointed to js\SA_system_emulation.min.js, so I tried replacing 0.32.0's js folder files with 0.27.2's (since 0.27.2 works every time) but it didn't solve the problem.

WORKAROUND:

Today, I moved 0.27.2's "XR Animator - electron-v31.0.1-win32-x64_SA" folder into the 0.32.0 folder and ran that electron.exe instead of the one in "XR Animator - electron-v33.2.0-win32-x64_SA". Now mocap works immediately every time.
