it appears it doesn't work if the "threads" parameter is >16
right now what you can do is move the "cpu usage" slider to the left to the point where it work

Thanks! That'll work for now.
Looks like it was trying to use 31 threads by default. Hopefully the thread count will be increased in the future.

After updating my SVP Pro client this afternoon to v4.3.0.190 (using the auto-updater/installer), I can no longer transcode any videos to HEVC. Any transcoding instantly fails. I have attempted to cleanly reinstall SVP and change any and all options that may help, with no success to get HEVC transcoding working again. Everything was working fine a few hours ago before the update.

I get the following error in the output log when attempting to transcode any videos to HEVC after the update today:
I don't use custom settings for HEVC trancoding in SVP, just the basic software encoder at CRF 18.

Any assistance with this would be appreciated!
