I'm using PyCharm, determined to learn the PipEnv virtualization tool(it utilizes SHA256 hashing against downloaded packages), and was experiencing this same exact error message (error 193, %1 not a valid win32 or whatever). I realize this isn't exactly your scenario however, you're using python and PyCharm so I figure it might and might help others who arrive here. Anyways...

The way I resolved it was by: 1.) in the 'Add Python Interpreter' window (first setting up virtualization interpreter), I had to put "C:\Users\ericm\AppData\Roaming\Python\Python38\Scripts\pipenv.exe" as my "Pipenv executable'. (After doing this, I began getting a permission error when trying to utilize it) 2.) I had to add my project's path into the "Working directory" (e.x. C:\Users\ericm\OneDrive\Documents\Programming\Python\NameOfProject)

No more errors of any kind and my app is fully working again.
