Macbook Pro sometimes sleeps by itself after booting!

Sometimes after switching on my Macbook Pro (2019 with touchbar), it switches on normally showing the desktop screen, then it turns black. I give it some seconds then press a key and it comes back on from sleep. Sometimes this doesn't work and I have to close it and reopen, press a key or press siri button, then it comes back up from sleep. Once it did this twice in a row. It is only a year and a half since I purchased it, so it is quite new, and it is updated to Big Sur. What can be the problem?

To troubleshoot start checking with "Energy Saver" tab in System Preferences.

Also check if you have same behaviour in safe mode.

How to use safe mode on your Mac - Apple Support

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
