Weird bug when running game

I’m making a small PS1 style game to learn unity as this is my 1st project on this app. I chose the in built 3D renderer and then on top of that I added a ps1 render pipeline which should probably work.
This is the one I used: GitHub - pastasfuture/com.hauntedpsx.render-pipelines.psx: A scriptable render pipeline for emulating Playstation-1-style graphics on contemporary hardware.

After changing every material’s shader to PSX, everything is perfect and visible on unity

However even when selecting all the scenes in the build settings, the .exe file only shows this screen

I’ve been searching for quite some time now and cannot seem to find a solution. If anyone had a similar problem or knew a solution it would be wonderful! Thank you!

obvious question is that if you had follow all the steps and if you are using the unity versions that the code is intended for

the pink stuff looks like something not working with the scriptable pipeline

Yes, after changing the unity version to an older one this was fixed. Thank you!
