what is your pc spec ?

try to switch to RHI 11 from the project setting > windows > RHI 11 or via engine config file if it crash immediately when opening.

I have an RTX 3070 with an i7-12700 with 16GB Ram and the engine is stored on my HDD, but that being said after re-installing it and resetting my 3D settings in nvidia control panel and updating my graphics driver and running it with administrator access it ended up working, im not sure how or why but it works now.
