B4J Question [problem gone] Occasional Debug crashes

[Didier9]

This is a bit hard to describe.
I am working on this program (the same for several years, just adding new features and fixing bugs) and it seems that recently I started getting crashes when I recompile in debug mode:

It does not do it every time but once it does it, I have to restart the IDE (or switch to release mode) then I am good again for a little while.
If I switch to release mode after it has crashed in debug mode, then it runs, but if I go back to debug without restarting, it will fail again.
It does it when I do an incremental live update and when I do a complete recompile.
I am using B4J v9.80.
It does it on multiple computers with the same project, 32 or 64 bits Windows 10 Pro with Oracle Java and 8 or 16 GB of RAM.
I am reluctant to post the entire project because it is very large, and it seems to be the only project that does it, so I do not have a small project that does it.
Some guidance as to what to do next to debug this will be appreciated.

even if you only modify files always use the
git add .
(this is not adding files, this is adding the changes to git)
then the process as you just said.
