Yes, I can see that this problem has popped up from time to time but I cannot find a solution that fixes it for me anywhere.
Everything seemed fine when I upgraded from Windows 10 to 11 recently but I went to render an image sequence today only to find the option missing:
I've tried re-installing as well as ensuring I have the HEIF Image Extensions installed but no luck so far.
I see that user SLVideo in the post here managed to get the issue resolved but doesn't say how exactly.
Does anybody know hoe to fix this problem?
