Mirillis fails to record after 47 seconds

[Enaych]

Today, while playing a Counter Strike Global Offensive competitive game, I started recording using Mirillis Action! from the warmup session and ended when I entered the comp lobby after winning the game. However, when I went to review my footage, the video had only 47 seconds of footage with about 1 second of audio followed by stuttering which lasted about 5 seconds of the ~30 minute game. I was not aware of this as my in-game HUD continuously notified me that it was recording the entire time. Is there any way to recover the footage as it's really important to me.

Well that's an ancient bug I thought was extinct...

What version do you have? And what specs?
