Xiaomi Pocophone F1 My storage is always full.

I have 64GB on my phone and until a month ago i was only using like 30 GB.

I started getting a lot of bug reports which had like 30-200 MB and I was getting enough to fill my storage. I had to delete them myself, they were annoying but not really a problem.

Now , I don't know why but my apps and data occupy 50 GB of storage and I don't have that many apps, I have 2 apps that have 2 GB and the rest have very little.

I only have  2.6 GB full and every twenty minutes or so I have to delete everything just so I can stay on my phone.

If you can help me pls tell me how.
