I have the same problem, when recording my screen. Is there a solution what to do? I tried uninstalling and reinstalling OBS but that didn't help either. I have emptied my D drive a lot but also not the problem fixer, what can I do?
I recorded 4 screenvideos before I got this message.
I tried to write them to my NAS and the videos appeared first, but after this warning -that I could not write my file due to lack of space or the ransomware filter was blocking it (this is not the problem because I don't have it on)- the videos were gone from my NAS.... how is this possible?
Can anyone let me know what else I can try to solve this :)
