We are migrating an old Delphi 2007 application to Delphi 10.3. The app uses a specific BPL written just for it (it is a standard in our company)
The BPL compiles fine, but after installing it, Delphi 10 shows an error box
The IDE hangs continuously showing the message. If I click "Ok" the error pops again and again even if neither mouse or keyboard are used. Must kill using task manager

If we cheat the IDE by first running it, manually installing the .bpl file no error is shown, but then, we can not open any project but the IDE responds: menus, mouse and keyboard but loading any project triggers the error. Even creating a new project triggers it
I've searched for days without finding a single page targeting this problem.
Any idea why this strange behavior is happening and how to solve it? Other programs with this approach (an application specific BPL) have no problem, but this is the first we are migrating from 2007
Edit: I tried deleting the .dproj file and openning the .dpr. That will force to create a new default one. No luck. Same behavior
