iPhone 13 storage full due to high System Data usage

Hello. I have my iphone 13 with 128gb storage. I couldn't open anything on my phone because the storage is too large but the main reason is my system data taken 80gb. Does anyone knows what should i do? I've tried offloading unused apps, but the storage just move to the system data and not clearing up the storage.

iPhone 13, iOS 18

When system data goes out of control, the way to solve this is to (preferably using your computer), backup, then restore your phone.
