Description: Can't record in MP4 since 3/11/2020 update

Ever since the 3/11/2020 update, I can't record any video in MP4, only in AVI. It was working fine prior to the update. I've tried installing K-Lite Codec Pack but that doesn't fix the problem and I've uninstalled and reinstalled Action! and the problem still persists. How do I fix this?

For reasons I can't understand, I can't record ANY video in MP4 since the 3/11/2020 (4.2.0) update. Prior to that, it was working fine but when I updated on 3/13/2020 it stopped working. I'm getting a green screen for the video and can only hear the audio. Now I can record in AVI, but that results in huge (30+ GB) videos and that's just too much for my 930 GB hard drive. I can (and did, the last time I recorded in MP4) use another software program to "recode" and drastically reduce the size of the video, but I shouldn't have to do that after every recording. I have tried uninstalling and reinstalling, but that hasn't fixed the problem. What's going on here and how do I fix this?

Nope. Still getting green video screen even after restarting computer.
