Slow and stuttering video [WIN10]

I have been using manycam for about 6 months now with no issues.

Now the video from my webcam is slow, lagging, and stutters a bit.

I run my camera in virtual cam at 30fps and 800x600 resolution.

My hardware
Windows 10
Ryzen 5 3600
16gb ram
512 SSD
Gpu GTX 1650
logitech web cam c930e
