Lock screen turns on automatically in 2 seconds after putting the phone on sleep

[aulis]

I have been facing a problem with my Samsung Galaxy M30. FYI The power button working totally fine(I can reboot using it and shut the phone down, no problem with my power button). But as I put my phone to sleep, the screen does go off but the problem is that after 2 or 3 seconds the lock screen of the phone automatically turns ON(without touching it or shaking, I haven't enabled any gestures) and continuously glows all the time, it doesn't turn off. I tried to shut down my phone but it didn't help me. How to troubleshoot this? This problem drains my battery too fast, I don't know what happened to my phone. Can it be a virus or malware problem(I have also tried to scan my phone for any malware but it also couldn't help me)?

Yes, like once I push power key, the screen turns off and gets locked, but then wakes up in 2 seconds and remain on forever.
And no the AOD doesn't comes up
