Hi @teqteqx,
I think you need to add a very large page file of virtual Memory like 128GB on your NV ram solid state system disk which I documented in another post
Install Pagefile.sys on Windows 10
In the size box type 128000 in both boxes
Then restart your PC.
There was a problem with C++ and Nanite content which crashed with an assertion and this fixes many problems.
If it works and you want to save space on the SVRAM disk then you can cut the value down but remember that other files may be bigger and will cause problems
