Having the same issue with a surface pro 6, i7 with 16gb. Any further suggestions regarding the help text?
Nope. Especially now you declared that you have a comparable model with more memory (16 GB) and better graphics engine which should be sufficient for this game running in 4K. If I had one and no important data on it, I would try it with a complete fresh install from USB-stick created with latest Windows media creator tool. But you need to be experienced in doing such things.
