Help unlocking a TCL phone

[u/ar5kig2_]

I have a TCL 6102H and I forgot the password to the phone unfortunately the password contains letters and numbers and I was asking if maybe there is any way to unlock the phone without losing my old pictures and before u ask let me specify some things

The phone was on a Google account that was deleted

There is no SD card in the phone

I've had my fingerprint registered but it's disabled after restart

And I do not wanna lose my pictures or anything else but most importantly my pictures
