Adobe PP 2019 (not responding)

I am fairly new to APP. So I got  APP and had a lot of issues on my PC (i7 8700k, 1080ti, win10, nvme ssds). For example my video playback would often stop working when making changes in the timeline.

I really needed to make a video while on vacation so I just bought a new Razer Blade 15. i7 9750 rtx 2070 ... fairly decent laptop. I figured my PC needed a clean install but my internet at work (afghanistan) is too slow and I didn't want to wait. Anyways I got the new laptop and installed APP and just started working on it ... but I havent even gotten to edit anything ... APP would freeze when importing several files at once ... the encoder would not respond in many/most situations ... and now I just tried to preview a click and APP went to not responding.

That is two machines that are pretty decent spec'd ... am I doing something wrong? These are clean installs ... or is APP just not that great anymore?
