My Samsung a54 is doing the same. The phone crashes, and the side button won't unlock the phone from the first press.. sometimes it takes about 3 minutes to be able to unlock the phone it's a new phone and still under warranty. Worst experience ever with Samsung. Please help.

I use Samsung Galaxy M51 and had a similar problem.

For may months my phone had this symptoms - 

• laggy UI
• Launcher will stop working and throw an error
• Screen Unlock and Fingerprint will either won't respond properly or lag

None of this worked

• I tried restarting the phone
• Clearing cache of UI 
• completely factory reset the phone 

I was about to give up on my phone and was sad about it and thought it was a hardware degradation. Then finally one fine day I found the root cause and fixed it.

This worked for me

• Change the launcher of your Phone

The launcher is buggy and there is nothing you can do to fix the Launcher so change the launcher. In my case, I used Lawnchair Launcher. This solved my problem.
