D12.1: Debugger Assertion Failure in pcntrlsrv.cpp

[hukmac 5]

Hello! 🙂

 

I'm working in Delphi 12.1 CE (patch 1) @Win10 22H2.

For many weeks Delphi IDE was running fine, but today it sudenly started showing message "Debugger Assertion Failure "" in pcntrlsrv.cpp at line 449" (in 64bit mode). I reverted changes in my project to the state in which this was not happening previously but this was not helpful. The exe of my app is being built properly and when run outside IDE it behaves correctly. But there is no possibility to run the code inside IDE with debugger (both in debug and in release mode IDE shows the above message). "Run without debugging" works fine, debugging in 32 bit mode also works fine.

 

Do you have any ideas what can be the reason for such behaviour and how to make the IDE/debugger to work properly in 64 bit mode again ? Restart of IDE, switching target, release/debug modes, erasing all dcus and restarting OS was not helpful.

 

Remark: I have found that similar problems were reported in the past but I found nothing about my failure (https://martinvirgil.wordpress.com/2012/09/05/delphi-assertion-failure-using-windows-7-64bit/)

Update: I have done additional check - created new project (one form, one button). Unfortunately behaviour is exactly as described above. So it is not related with the project. Any ideas how to fix it? Have anyone had such an issue and maybe fixed it by reinstalling IDE?

Antivirus / security software can mess up debugging. Excluding the IDE (bds.exe) sometimes helps with odd errors that seem to start happening without changes in code or the IDE.

Thank you for the idea. No antivirus/security in the system except the Win built-in one. But I will investigate it.
