Hey there @AlasTMT! Welcome to the community! The top level of the error seem to be pointing to an Nvidia graphical DLL nvrtum64. Much like the following DLL nvwgf2umx in the error, there are a number of possible solutions in this thread (mostly geared toward Unreal Engine itself instead of UEFN and primarily for the nvwgf2umx.dll related errors but may assist in this one as well)
Some of these options may not be applicable to UEFN**
