I did made this investigation and report it to embarcadero QA portal: Install windows 10 in a VM, install delphi 11.1. Create a RadServer project from template. Result : I am running into the same issue. So it is 100% in the hand of embarcadero. 

I have exactly the same problem than  Lajos Juhász in Alexandria 11.1. I did only use the RadServer template.  So it is not something to do with my code or large project. As soon as I change something (I change a comment), then  I get the internal error.  I did apply 11.1 Update 1 patch but it does not fix the issue. I did also install the patch for people working in Windows 11 (I am working in Windows 10) but it does not help.

Note that there is a Defect (RSP-37631) entered in https://quality.embarcadero.com/ 

I do suspect that it has to do with Visual Studio installed on the same machine (I have Visual Studio 2019). I have seen this in the quality portal for related defect.

Could you (@Lajos Juhász ) tell us If you have Visual Studio installed?
