I can think of a couple reasons for this:
-
The
git diff
between local and master branch is wedging your project by creating an infinite loop. -
The Editor is having to recompile shaders (or build assets if compiling from UE4 source). This can take alot of time and CPU/GPU. If your PU’s are maxed out, wait for it to finish (overnight).
-
There is some intermediate file stinking up your beans. Delete the “saved” and “intermediate” folders, and right-click the .uproject to “Generate Visual Studio Files”
If the process is actually “suspended”, I have no idea.
