With a fresh install or an existing install of Shotcut 22.10.22, pressing "?" from the main window, or invoking Help -> "Actions and Shortcuts" causes the application to crash to desktop.
Both the 22.10.22 and the 22.10.25 portable version downloaded from Shotcut directly does not exhibit the same behavior.
Install Path: I:\PortableApps\PortableApps\ShotcutPortable
New installation
Windows version: 10 Pro 21H2 64-bit
It looks like there's a bug in Shotcut that will cause a crash on the actions and shortcuts Help when using the --appdata command line switch, which is how we tell it where to find its files. I'm writing up a bug report for the publisher now.

Sometimes, the impossible can become possible, if you're awesome!
This has been fixed by the publisher for the upcoming 22.12 release.
