I am not facing any issues with screen protector. Few things to keep in mind
1. Buy tempered glass which supports ultrasonic sensor
2. Re register your finger print after applying new tempered glass
3. Increase touch sensitivity from settings.
Please accept solution if it is helpful.
Thank you!

Check with local shops they know what works well with Samsung ultrasonic sensor.

Re-register Fingerprints:

• After installing a screen protector, the sensitivity of the fingerprint sensor may change. Delete the existing fingerprints and register them again with the screen protector on. This can help the sensor adjust to the new surface.

Adjust Touch Sensitivity:

• Go to Settings > Display and turn on the Touch Sensitivity option. This increases the screen's sensitivity, making it easier for the fingerprint sensor to work through a protector.

Use a Wet Finger:

• Lightly dampen your finger before scanning. Some users find this improves the sensor's ability to detect fingerprints, especially with a protector installed.

Clear Cache Partition:

• Boot into Recovery Mode and clear the cache partition. This won't delete any data but can help with sensor-related issues:
  • Turn off your phone.
  • Press and hold the Volume Up button and the Power button until the Samsung logo appears.
  • Use the volume buttons to navigate to Wipe Cache Partition and select it with the Power button.
  • Once done, select Reboot system now.
