Good afternoon, I first encountered such a problem:
When I build a project, an error occurs:
I start VS19 as an administrator

My guess is Visual studio can’t write to EXEC because it is currently running. (But in general this error means that Visual studio can’t modify some file)
This is strange, if I close the project and editor, then delete temporary files(binary, vs, etc), then it builds.

I ran into the same problem when the compiler tried to modify various DDL files.
I fired up [process explorer][1] (free) > ctrl+f > and pasted one of the blocked DLLs in the search box
There was no Crash Report window open, but nevertheless it looked like both the UE4Editor and a CrashReport process kept my DDL files in memory. I clicked the CrashReport to select it in process explorers main window and killed the process, then I closed my editor. I was now able to compile the project in Rider.
it works for me thanks, i delete binary files
