Crashing on h264 Encoding

[Selur]

I used to have a global (created in 2018) which if loaded would preserve my h264 settings.

No way to reproduce this, without the global profiles.
-> zip the profile and share it with me and I can look into it.

Regarding your crash:
What happens if you call:

"C:/PROGRA~1/Hybrid\64bit\ffmbc.exe" -y  -r 24000/1001 -i "G:\STOCKSY\mfive\CITYAT~1\h264\12_29_02_7610_02.mkv" -vcodec copy -map 0:0 -metadata encoding_tool="Hybrid 2020.02.19.1"  -aspect 177778:100000 -r 24000/1001 -f mov "G:\STOCKSY\mfive\cityatnight\h264\3117800.mov"

inside a Windows Command prompt?
