Hybrid 2022.03.20.1: No module named 'vsdpir'

[Dan64]

No, this was not my test condition. In order to be sure that the proper Vapoursynth version was loaded. I opened a command window in the directory "D:\Programs\Hybrid\64bit\Vapoursynth" where is located the "Vapoursynth.dll" used by Hybrid, then I executed the commands described in my previous post, and in this case I received the error regarding the DLL already loaded. In my tests with vsViewer the error was related to y4m header. But fixing the problem of DLLs path fixed also the problem regarding the y4m header.
