fatal error C1083: Cannot open compiler generated file: '': Invalid argument

I tried putting the whole log in, but it was too long. Here's the ending error message:

Researching around, some peole seem to get this issue when the build path is too long? Notes;

• a small amount of shortening the path did not fix it C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\dectron\detectron2\layers\csrc\box_iou_rotated->C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\d\detectron2\layers\csrc\box_iou_rotated
• deleting all contents of box_iou_rotated_cpu.cppand building generates the same error
