Screen is too sensitive after Android 10 Upgrade

After the Android 10 Update the screen on my Fairphone 3 is too sensitive. For a short moment the phone accepts to many Inputs and does what it wants. Or it freezes and i can do nothing. The only way to get arround this problem is to lock the phone. How can i fix this?
