Hello @GordianDotNet I have the following problem.

Windows 11 Pro Visual Studio 17.9.5 VSMonoDebugger2022 2.2209.1806

After start "Deploy, Rund and Debug" I get the following message:

[VSMonoDebugger] Debugging cannot be started. An error has occurred, which usually indicates a faulty installation (code 0x80020154).

I have repaired Visual Studio and even a new installation did not help.

[VSMonoDebugger-Log] 2024-04-03 09:25:49.6001|TRACE|VSMonoDebugger.Debuggers.SSHDebuggerBase|Entering: DeployRunAndDebugAsync - SSHDebuggerBase.cs(24) 2024-04-03 09:25:49.6001|TRACE|VSMonoDebugger.Debuggers.SSHDebuggerBase|Entering: StartDebuggerAsync - SSHDebuggerBase.cs(45) 2024-04-03 09:25:49.6001|TRACE|VSMonoDebugger.MonoVisualStudioExtension|Entering: AttachMonoDebuggerToRunningProcess - MonoVisualStudioExtension.cs(369) 2024-04-03 09:25:49.6001|INFO|VSMonoDebugger.Debuggers.SSHDebuggerBase|StartDebuggerAsync - deploy 2024-04-03 09:25:49.8036|ERROR|VSMonoDebugger.MonoVisualStudioExtension|Catched: AttachMonoDebuggerToRunningProcess - MonoVisualStudioExtension.cs(393)|System.Runtime.InteropServices.COMException (0x89710015): Debugging cannot be started.

On my notebook everything works without problems, I also use Visual Studio 17.9.5 and VSMonoDebugger 2..2209.1806.

Thank you.

Hello, I've had the same issue on my Visual Studio 17.9.7. But if I downgrade my Visual studio to 17.3.4 it appears to work normally. So maybe the extension is not well supported for higher version of VS?

The specific thing causing the error is int hr = dbg.LaunchDebugTargets(1, pInfo) @ MonoVisualStudioExtension.cs(line 388). It returns an invalid code, which then makes Marshal.ThrowExceptionFromHR(hr) on the next line throw an exception. I tried fixing this issue myself but unfortunately got nowhere. The exact error code seems to be REGDB_E_CLASSNOTREG, where a COM class wasn't registered, possibly due to the debugger updating and changing some things?

On another note, any other debuggers that people use that work? I've tried half a dozen different approaches and none have worked. I would really like to be able to debug my code but alas, nothing.
