When rendering video project, some plug ins flashing then turning off totally in final render-ie:background generator, auto pan and probably more. tried video card acceleration off and on, Tried 2 different computers to no avail. Both are intel 1. 8th gen, nvidia 1080ti2. 2. 11th gen/nvidia, 3080. newest ver 20, build 411 of vegas pro. So can't use quite a lot of plug ins for editing-4k or 1080p footage. Tried many different res for render-no difference. Rendered fine if using basic plug ins like brightness/contrast-face smoothing and normal transitions.
