[HELP] Getting Hybrid/Vapoursynth running again in W10

[Miranda]

Uninstalled old Hybrid and installed latest Dev version. With no filters and when running preview I get:

2026-07-17 16:04:36.093
Plugin C:/Program Files/Hybrid/64bit/vsfilters/DenoiseFilter/NEO_FFT3DFilter/neo-fft3d.dll is using API3 which is deprecated and will be removed shortly.

I can confirm

C:/Program Files/Hybrid/64bit/vsfilters/Support/std.dll

is missing

Seems like a typo somewhere, which caused Hybrid to load an empty dll,....
What filters did you activate?
DebugOutput?
.....

[Miranda]

No filters loaded at all. output set to ProRes 422. I'll run the job and get a debug.

[Selur]

Make a debug output of the Vapoursynth Preview,...

Attached.

As I said elsewhere on this forum, it used to run fine on this W10 PC but it stopped working a few months ago after a Hybrid update.

I haven't been able to get it running on my new W11 PC (it keeps crashing the PC) nor my Mac (too complicated to install), so I'm really stuck now and am Hybrid-less.

ps: I hope you have recovered from the flu.

Okay, you are using QTGMC with a non-avx2 capable cpu,...
I see where the problem is.
Switching "Filtering->Vapoursynth->Misc->Prefer->Expression handler" to something other than 'std' should work.
=> uploaded a new dev which should fix that
'std' is a valid choice, but probably the slowest => I would recommend trying the other "Expression handler")

Perfect, now works great. Thank you
