I tried disk usage but just shows a bunch of green squares and nothing related to system files. The biggest files in diskusage were whatsapp videos of 14mb.
If you have a PC there are some development tools that can help diagnosis, including system files.
Otherwise if you can afford to do so, it is recommended to try resetting to factory settings. You should read about what that involves before doing so.

I will do that later if I can’t find a solution. It will, at least, separate my sd card from the main storage.
