hidden volume now asks me to format every time I try to open it

I've had veracrypt for this volume for almost 2 years now I think

I do have a decoy volume but I'm sure I haven't downloaded anything extra in it and that it's not the reason for my hidden volume acting like this. I'll describe the timeline below:

- Mounting the hidden like usual and then I can't open it it shows the format pop up, if I close it it just tells me it's not accessible

- I try the same thing again and again, then update veracrypt (it was way older than the most recent update) and it actually works I'm able to open my drive see all the folders and files, didn't get to check if everything works properly because my laptop decided to shut itself down (ran out of charge) right then

- back to original error

Would really appreciate a fix/any help it's got so much stuff that I would hate to lose and I didn't make a backup.. kept putting it off for later
