[HELP] Vapoursynth Preview Sometimes not working or taking so much time but will not open

[Selur]

Vapoursynth has a portable version which Hybrid used (combined with a portable Python version), but Vapoursynth could also be installed system-wide.
Problem: Vapoursynth does not allow stopping autoloading, so if a system-wide install is present it might cause problems with the portable version, especially if it's using a different Vapoursynth or Python version.
