So, I got past the error, but I have no idea how to fix it in future.
My machine just happened to have a major windows update ready (I would have been on second latest version), and after updating windows, it now works. I assume it replaced some possibly corrupted DLL...
Hi David,
The Windows update indeed seems to be the culprit here. It may already have hijacked something which Studio Pro needs to start.
Glad to hear it’s resolved now.
