Hello @DeadMuppet and may I extend a Warm Welcome to the Samsung Community Forum 👍
I'm sorry to learn of the issues your currently experiencing with your Biometrics.
You can go into your Biometrics Settings to test your fingerprints that have been set up.
Personally on my phone I scan the same thumbprint x 3 times which helps it work all the time for me then.
I have the screen sensitivity turned On too in the Display Settings.
Some people who have dry skin may experience issues. Gently breathing on the finger can help in those circumstances.

This is a generic troubleshooting step >
- Clear Cache Files from the phone's System Partition Section > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's }
Obviously there are alternatives such as face unlock, pin or pattern that can be used alternatively.
If you perform a forum search you may find existing threads with some further help or guidence within.
If i can be of any further help please don't hesitate to ask 😎
