error helper 1

[VCRvideocapturing]

It was working fine and this happened all of a sudden?

Assuming you didn't change anything in Hybrid, it must be something outside of Hybrid interfering.

No details, no debug output, no clue what you are really doing.
Sorry, but I don't see how I could help.

Fixed it
I changed the encoding to 1 pass
Switched back to 2 pass encoding and it's working fine, but when you add any denoise filter like

Filtering tab} DeNoise
Tick mclean
Then you get the helper 1 error, if I uncheck mClean and encode it works fine.

Can you test from your end please?
Add a file choose filtering tab (3rd option in menu)
Sub menu Avisynth tab  } DeNoise option (6th option in sub menu and select/tick the 3rd option (mClean) and encode with .mp4 as default container, you should get aborting video file name due to: Helper 1, exit code -1313558101
