I have a small problem with the fingerprint reader of my Sony Xperia x every time I want to register the fingerprint it gives me fault and asks me to free up space and try again I already did it and also restart it from the factory that I can do

Just a wild guess.

Goto settings->apps & notifications-> App info

Tap the 3 dots in the upper right corner->show system

Find Fingerprint ASM -> force stop then restart

(I noticed no change whatever so I guess it doesn't help you)

Other choice

Restart in Safe Mode  (switch off with the power button and then long-press the restart button)

Does the fingerprint act as expected in safe mode?

Did you clean your fingerprint sensor?
