New Finger print sensor light animation error (xiaomi mi 9t)

[Mohannad]

Hello, I've an error with my xiaomi mi 9t finger print light animation. When I move my phone from a table or something or from my pocket the finger print light animation is turned off, not all the time but most of the time, like 95% it's turned off.
I've the latest software update and I've a tempered glass screen protector, is the screen protector causing this error or is it something else?
Please help and excuse me for my bad english... Thanks in advance
