I have recently reinstalled Steam due to try and troubleshoot the Screenshot/Game Recording manager from crashing (which didn't help) and manually backed up my screenshots and game recording folders, but I unfortunately only backed up the clips sub-folder and none of the others, such as background or timeline, which I realise now was a mistake.

My clips are showing up fine in Steam and can be played/edited, but I get an error message when trying to export or quick share which I assume is because I'm missing the other files. I would appreciate it if anyone could inform me of a potential fix. I haven't had any luck recovering the files I need and manually working around each file isn't that viable for me due to the number of clips I have.
