Executable fails with "Failed to execute script pyiboot01_bootstrap" message
I am running on Windows 10 and using PyCharm 19. Everything is up-to-date except that I'm still running W10 1803. I have previously successfully built executables with other Python programs. The program I am trying to package runs w/o difficulties under the interpreter.
The current problem is that the executable crashes and when I run with --debug, I get the failure message: "Failed to execute script pyiboot01_bootstrap"
The program isn't particularly complex, though it does use some Google APIs to access a spreadsheet on Googledocs.
I'm at a loss as to what to try next, and would appreciate any help I can get.
