Folders have disappeared???

I have all my photos on Google drive but in folders rather than in photos. I have albums dated 2013 up to this year and then an ‘old pics’ album.

I’ve went into Google drive today and the only folders there are 2022-2025. Everything else is gone. I refreshed it and 2018 popped up, but I went into it and it was empty. I came back out of it and it wasn’t there? I then checked on my phone and could see 2013, but when I refreshed the page it was gone.

Info:

• nothing of note on the activity log
• no one else has access
• I absolutely have enough storage, I pay for 100GB and I’m using 13GB at the moment

Help????
