If you could post your debug log I would take a look later, this might be helpful. There is also an env var if you know how to set it:

press windows key + run, then type cmd to enter command line...

Then type this , press enter

set "BLP_DEBUG_ENABLED=1"

then run this

calibre-debug -g

But the debug log without the env var is helpful too.

Tricky part is to copy the output: if you click the cmd icon on the top left side of the window title, you'll find an Edit - Select all option, then you just right click and paste on notepad
