videowriter crashes when run using pyinstaller - python-3.x

Question

For the past several weeks I have been using videowriter.write() and it has been working fine. I needed to give the program to several coworkers that have random python installations so I packaged it up in pyinstaller, which I have used successfully on other projects.
Almost everything seems to be working fine when run under pyinstaller, I can read images, capture images from the camera, show them on the screen, and write out individual images. The problem is that when I use videowriter.write() somewhere down in the bowels of the code it crashes, complaining that the images have the incorrect size. This only happens when running under pyinstaller, not when running it directly from python.
Below is a portion of the code that I extracted with a generated test image. A coworker tried to run the same example, using his copy of opencv, python, and pyinstaller and his executable seems to work. I spent the last several days trying to duplicate that setup but I don't get the same results. I have completely removed python 3 (I have a copy of 2.7 that is specifically for other tests), cleared the pip cache, cleared environment variables, and made sure all the python directories were removed prior to re-installation. I have tried python back to 3.7, different versions of opencv 4.1 through current, and all behave the same way. I have also tried using a virtual environment and setting up the core python sitting in Program Files.
The current version of opencv_videoio_ffmpeg is: opencv_videoio_ffmpeg420_64.dll.
The version that my coworker used successfully is opencv_ffmpeg410_64.dll
While it doesn't seem to make much difference, the command I have been using to build the executable is:
pyinstaller videowriter_test.py --onefile
I have also tried it without the --onefile option, it works the same but its a little harder to find the executable.
The python installation has the following installed: opencv-python, opencv-contrib-python, imutils, pynput, keyboard, virtualenv, pyinstaller. These were all installed using pip.

If I run the using idle or pyCharm, I get this result:

if I run it from the virtual environment I get:

One interesting note is what I assume is the temp directory that is referenced in the first error message. I have no idea where the directory comes from and what happens to it, it is missing when I go looking for it.
Any suggestions?
