Running BIAB 2019 644 64 bits Windows 10.

BIAB starts correctly when launched from the start menu or when clicking a shortcut to its .exe, then opening a SGU or MGU file from the BIAB open menu works OK and all is file (I only use these file types with BIAB).

Problem is when clicking on the same SGU or MGU file in file explorer: BIAB starts and open its main window, but this window only contains the text menu bar ( "file", "edit", ... "help" ) and nothing else.

Trying to open a file using the "file -> open" menu does not work, nothin happens. But "file->exit" works so program isn't totally dead.

One point: in between clicking inside file explorer window and the opening of BIAB main window, I can see a very temporary appearance of a small window at the bottom right of the display, similar to those in which BIAB displays messages for instance when exporting audio, but this windows disappears immediately so there is no way to see what is displayed in it, which could give an idea of what's happening.

Since clicking on a file name launches BIAB correctly, the problem is likely not due to association problems. and since BIAB works OK when launched when opening a file, there is likely no style building problems

How to debug that ?
I tried some options to obtain a log file in the BIAB data folder, but nothing was of help.
