I notice you have MadExcept installed. Do you happen to have a MadExcept log file of the crash? Or at least a stack trace? I cannot reproduce the problem with my installation. But I have way fewer components installed and I think your IDE is a higher SKU than the Pro I have got.
Did you try to compile the latest GExperts sources and use the DLL produced by that? The bug might already have been fixed. Here are the instructions for doing that.
Unfortunately there’s no madExcept log file of the crash. I have a Delphi Pro license.
I haven’t tried to compile the latest sources. There was no issue in Delphi 12.
