Hi Mark,
Thanks for the recommendations.
I checked and indeed libomp140.dll is missing both in the system and in the UE installation folder.
I downloaded (from https://www.dllme.com/dll/files/libomp140_x86_64) and installed (copied) the library to the system.
After that, the project loaded without errors in the log and the plugin eventually started. I have not yet checked how correctly it works.
By the way, I am not using Windows 11, but Windows 10 x64 Pro.
Thanks again for helping me solve this problem.
Best regards,
Vit
