Power Automate Desktop crashes when using “Run from here”. Normal execution/debug may work, but “Run from here” throws:

System.ArgumentException: Delegate to an instance method cannot have null 'this' in Microsoft.Flow.RPA.Desktop.Robin.Core.Types.TypeChecker.IsList, from Designer.Application.ProgramExecution.Debugger.FlowRunner_AfterRunning.

I have the same issue, it seems it started after the update in June.
In unattended mode everything works. In attended mode Run also works fine, the problem is with "Run from here"

If you found a workaround, please let me know

That completely confirms it. Since it runs flawlessly in unattended mode and during full attended runs, your automation logic is perfect. This is a clear regression bug introduced in the recent update where the designer's debugger engine crashes specifically on a "Run from here" command.

While we wait for a official hotfix, could you check if the Breakpoint workaround keeps you moving?
Instead of using "Run from here," try placing a Breakpoint on the exact action you want to test, then run the entire flow from the absolute beginning. The flow should execute normally, pause on your breakpoint, and let you debug that specific section without crashing the designer.

In parallel, since multiple people are hitting this exact same stack trace on version 2.69, please open a support ticket with Microsoft and provide the Correlation ID from your logs.
