Hybrid 2022.03.20.1: No module named 'vsdpir'

Does it work for you is you copy the files into the Vapoursynth\Lib\site-packages\onnxruntime\capi folder and add that folder to the PATH variable?
I just checked and it sees like installing onnxruntime did add the path on my system.

Hmm,.. that's probably not it either, I remoed the path from PATH rebootet the system and it's still working here. :/
my PATH contains:

C:\Python37\Scripts\;C:\Python37\;C:\Windows\System32;C:\Windows;C:\Windows\System32\wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\Kensington\TrackballWorks;C:\Windows\System32;C:\Windows;C:\Windows\System32\wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;C:\Program Files\NVIDIA Corporation\NVIDIA NvDLISR;C:\Windows\System32;C:\Windows;C:\Windows\System32\wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;C:\Program Files\Calibre2\;C:\Program Files (x86)\GnuPG\bin;C:\Program Files\PuTTY\;C:\Program Files\Git\cmd;"C:\Users\Selur\AppData\Local\Microsoft\WindowsApps;";

nothing that should be related to Vapoursynth&co.

Or may be it does, I noticed a __pycache__ folder inside the capi folder, deleting that and it doesn't work here either.
-> okay, this might be a hint.
