LaunchBox cannot launch anything: "Unknown Error"

LaunchBox has been working great for me for a few years now, no issues. Yesterday, it simply decided to stop working altogether. All my attempts to launch any game, either archived or not, via any emulator, results in a window dialog box with the message "An error occurred while trying to launch the game: Unknown error (0xffffffffe)"

I enabled the debug logs, but it doesn't show anything new, really, just  "2023-04-01 04:58:52 PM FIRST CHANCE EXCEPTION: Unknown error (0xfffffffe)
   at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)"
after the games' extraction from its 7zip archive is complete (which the log shows is working fine)

Whether the game is in an archive or not doesn't matter anyway, it fails with the same message.

Nothing about my environment has changed between everything working and now nothing, so I'm not sure where to even start looking to figure out what happened.
