Mongodb Compass dialog not opening

Win11 x64 here:
I tried upgrading from a very old version (1.25.0) to 1.39.0, but no Compass shows up after launching. 3x compass processes are launched, but they do nothing. A log file is created, but not closed.

Happens regardless of .exe or .msi, but the 1.39.0-beta.2 worked here, at least in MSI.
