Macbook screen turning shortly after powering it on

I have a 2019 Macbook Pro and almost every-time I power it on and log in the screen turns black shortly after. The laptop is on, the screen just turns black like it is asleep and I have to plug it in to the charger for the screen to come back on. This happens at what appears to be any battery percentage. The laptop could have 45% battery and this still happens. It is very odd. Any assistance with this would be greatly appreciated.

Try resetting the SMC https://support.apple.com/en-us/HT201295

if no resolve—

To trouble shoot further you can:

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test will take a little longer as caches get rebuilt.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.
