ide Crash when copy a control CTRL+C

[Lorenzo B 1]

hello,

I have never created FMX applications, I have always used only VCL. Lately however I needed to develop a simple application for windows, which would have been better to do in FMX, but I immediately noticed a very strange problem. Basically if I try to copy any control into the form, as soon as I press CTRL+C the IDE crashes. I am using Delphi 12.2, but I also have Delphi 10.4 installed, I tried to do the same thing in that version, and I have the same problem there too.

If instead of using CTRL+C I use Copy from the menu, everything works and I can copy and paste without problems.

I thought it could depend on some helper shell that I use (MMX or CnPack) but I checked and I found nothing, but I have not tried to uninstall them!

Below I have put the extract of what comes out when the IDE goes into "general protection fault". 

Does anyone have any ideas about this?

Your call stack does not indicate that the call is going through an ide expert.

 

Additionally you don't need to really uninstall the experts. For some of them (but not for gexpoerts) you can temporary disable their package directly from the IDE. Not even need to restart the IDE.
Or use \CnPack\CnManageWiz.exe to manage your installed IDE experts (IDE restart required).
