Debugger activation problems in AS6.3.4.31

Hi Simon,
I’ve marked the issue as solved, but that’s only true for the PLC. When downgrading to version 6.3.4, the simulation enters a strange state — it appears to be in run mode (both in ARsim and AS), and all programs on the target match those in the project, but it doesn’t actually run. The debugger shows this dialog:


I’ve tried all the usual tricks (rebuild, restart PC, offline commissioning, clear configuration, delete Temp and binary files, etc.), but none of them work.
Do you have any idea how to deal with this?
Thank you
Regards
