I have recently bought lenovo Ryzen 5 3500u with radeon vega 8 GPU specially for video editing in premier pro but  I'm facing horrible playback laggings and frame drops. Now what to do ? It was my hard earned money but not able use premier pro. Even I tried 2019 and 2020 both versions but nothing happened. Please help me...

You might want to provide a little more detail about the system and also what kind of media you're working with. (Codec, framerate, frame size?)

My guess is that this (presumably) laptop is going to be on the very low end of the minimum specs to run the software, and if you're not using optimized media it's quickly going to choke that thing.

You should also have your media and cache on an SSD, not a HDD. You may need a larger SSD.

Also, as was asked:
