After all, it can happily run on a 20+ years old PC with W95 or XP also, so if changing to your brand new Dell would help, it is probably because the differences in the installation, not because of the better PC.
Completely agree with A_Camera on this, it will 99% be a windows issue and not UCCNC or the controller. I have installed over 30 AXBB-E controllers since Xmas and most are running on Refurbished Dell PC's which are low spec compared to your i7 laptop and running on Win7, 8, and 10 without any issues if using V1.12111.
I have had a couple of issues with the development versions but these mostly revolved around low memory, it seems the new Development versions are more memory intense so if memory is on the low side, which the Refurbs tend to be then occasionally it would crash.

I'm not a Windows OS guru so follow the guy's suggestions and I'm sure you'll find the cause.
