What is the MediaInfo on the video clips you are trying to use?

@RogerS I've tried reseting and clearing cache. My laptop meets all the system requirements. A lesser specced laptop can run vegas, no problem. It has an Intel CPU tho not and AMD one. But I dont know how that's a problem. Is it picking up my Redeon Graphics? It shouldnt right? It runs Adobe products just fine.

@jetdv The video clips are standard MP4 stuff. nothing I havent used before on other systems with vegas. It imports them. I can see it. When I play it back it freezes and "Not Responding". Every. Single. Time.

Please provided the requested information if you want assistance as details matter.

MP4 isn't an answer for media. MediaInfo is the way to do that and helpfully there is a link above to follow.

Intel isn't an answer for CPU. Which Intel?

Yes of course it will work with Radeon Graphics as the integrated GPU, so that driver also matters.

Did you load the known good project and media? What happens when you did?

@RogerS
1. The reason why I didn't feel the need to give you more information about the Intel CPU is because that laptop doesn't have any issues running Vegas. My point was that my other lesser specced laptop (which is without question) can run Vegas but this one which on paper has better specs cant. Hence I gave all the necessary info required for this laptop (The HP Omen). But if that helps, its an i7 8th Gen. But that doesn't have any issues.
2. HP OMEN (The one that has this weird problem) :-
GPU - Nvidia GeForce GTX 1660 Ti
Processor- AMD Ryzen 5 4600H with Radeon Graphics, 3000 Mhz, 6 Core(s), 12 Logical Processor(s)
RAM - 16 GB
Shouldn't it be able to run with Nvidia GPU I have?
3. The MP4 format to give more information is a NVidia screen captured recording that saves it in MP4 format:
1920x1080 , Data rate 9302 kbps, total bit rate 9433 kbps, 26.43 FPS, VLC media file (.mp4) (.mp4).
I have edited with these recordings or similar mp4 videos all the time on Vegas. Vegas usually supports higher quality professional footage formats as well like XDCAM/XAVC and it shouldn't have problems with this format either.
4. I don't want it to work with Radeon Graphics, as the Nvidia GeForce as it's GPU should be better? during gpu acceleration I have 3 options > off , Nvidia (my gpu), AMD (the integrated graphics driver that the CPU I guess has?) Is it a mobile processor? is that the issue?
5. I've known good project with it's media as a benchmark test and it gives the same problem. within 3 secs of interacting with it (just clicking the individual videos, nothing else). It freezes and "not responding" window opens if i try to close it. I'll try attaching an image.

Hope these answer some of your questions. This is so bizarre and frustrating as I have edited on other systems and don't see how it wont on this one, which is clearly a higher specced laptop.
I appreciate your assistance.

And the type of framerate is???

@Rudradeb, can you follow the link in my post and give exactly the type of video is in that MP4 file? MP4 is like a paper sack. I can put all kinds of things in that paper sack. We need to know exactly what is in your "paper sack" - i.e. mp4 file. Here's the link again:

@jetdv I understand you want to understand what exactly my MP4 format is (It has no problem importing the media and running it, I am fairly certain the problem is not the format of the video), but I don't understand how that is important since I've tried opening and playing the known good project with it's media as a benchmark test as suggested by @RogerS and those media files are in the format that 100% should be supported by Vegas Pro. Same thing happens. I am waiting for his response to the "known good project" result.
I don't think focusing on what MP4 format the video "I" was using to report this problem is going to help. Regardless of any media files I use, it does the same thing. It imports it, it works completely as it should for a few seconds and then it does what it does (as I've mentioned).
Additonally, I have given a few other thing's that have been suggested as well.
