Obsidian "forgetting" my vault

Hi all, so a weird thing just happened. I have 3 vaults on my windows laptop, 2 of which are synced with my Android phone via Obsidian Sync. It works perfectly fine.

This morning, I launched Obsidian on my computer and it just showed me the opening screen with no vaults, as if I just installed a fresh version of the program.

Weird, but I just opened my main vault which was instantly indexed, and all seemed well, but why did Obsidian “forget” my vaults like that?

The thing that is annoying is that I have to reconnect to my remote vaults with Sync and I don’t know the password so that’s a bummer
