Haptics not working

Hello, since some time my haptics on my iphone 11 have (nearly) completely stopped working. I have tried the usual fixes:

-restarting

-accesi itlity - vi ration

-tones&haptics - ringtones - haptics (here it also doesnt vibrate when i select other patterns)

-update ios 18.1.1

I read some other people encountered that issue with an IOS update.

I think the vibration motor theoretically still works because i recieved some random vibration today , but i couldnt replicate it.

Can you please help me fix that? Vibration is very important for me.
