So, today I found that absolutely all of my tab groups have been wiped from existence. Not passwords, bookmarks, history, extensions or anything of the sort. Just tab groups specifically. Everything else in my profile is still here. I tried restoring from a backup using the Session History Scrounger at https://www.jeffersonscher.com/ffu/scrounger.html but my closest backup was a March 26th one that is missing an entire tab group created after that date. I tried searching other solutions to my issue, but nothing has worked so far. It doesn't have anything to do with updates as the last one happened on March 26th and I definitely used the tab groups after that point. I'm at a complete loss on what I am supposed to do, as I lost ~600 tabs combined across all groups
