Blocked application permanent - no cleanup - Help!

Hi.
I accidently ran the old script 3.5.0 and now the Block Application function never cleans, the block is “permanent”. How do I clean it?

Paniced a bit here but I found the solution myself.

If anyone wonders…

Delete the key Debugger under HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
