After Effects 2020 v18 (and v17.7) does not want to start
Adobe After Effects v17.7 and v18 both don't start on my PC.
The window looks like this:

Notice the double menu bar. It hangs there forever. The only thing I can do is kill the application.
I've renamed C:\Users\<username>\AppData\Roaming\Adobe\Common to Common.old, and renamed all After Effects version folders in C:\Users\<username>\AppData\Roaming\Adobe\After Effects as well. No joy.
I updated my NVidia RTX 2080 SUPER drivers. Tried the latest "Gameready" driver and the latest "Studio" driver, both to v461.72. No improvement wrt After Effects.
Of course I also rebooted my PC (running Windows 10 64 bit fully updated).
After Effects just does not want to start. Is there any debug log I can view somehow that will show me what the issue could be?
