Dr. Memory fails to start. Crashes.

[Pacifica Research]

I've installed both Dr. Memory and DynamoRIO as external tools in VS2022. My app won't start under Dr.M. Notepad won't start under Dr.M either. My app starts and runs under DynamoRIO, but doesn't show errors, and I don't know where its logs are.

I've tried the latest vers 1.26 and also 1.25. Both crash the same way, instantly, with my app never starting. Same when trying to run notepad.exe. I've tried all the -debug and -light switches. Made no difference. Disabled anti-virus and firewall, no difference.

This is Win10, Ver 22H2, Build 19045.3570. On the metal, not HyperV. AMD Ryzen5, 6core, 32Gb RAM, VS2022 Community.
