Convert to video timeline unclickable

[gyelhsa]

This is a problem that has started in the past week or so. I make GIFs using Photoshop 2021 and after loading all my layers into frames, I would normally convert to a video timeline, merge all my layers into a smart objects and use an action to sharpen. I cannot click on the conver to video timeline; the button is there but it doesn't let me actually use it. It's greyed out and when I hover my mouse over it, it shows up as the blocked 'unavailble' cursor. Any way to fix this?

Same problem here. I noticed that the 'render video' option has disappeared. This is most upsetting because I just got into making timelapse videos...
