Why is Pyinstaller executable returning error '[19544] Failed to execute script due to unhandled exception!'

I have a Plotly dashboard that I am trying to turn into a executable for distribution. Pyinstaller runs without error but when I try and run the exe I get the following errors (in cmd).

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Andres\\OneDrive\\Documents\\Automation\\dashboard_tool_v2.0\\dist\\run_dashboard\\dash\\dcc\\package-info.json'
[19544] Failed to execute script 'run_dashboard' due to unhandled exception!

I use the anaconda environment so I've added the following to the spec file to assure it finds all the correct modules. I have also added numpy to the hiddenimports because in the warn-run file it says it is missing a ton of basic numpy functions. you may also see os because I have a second .py file it needs to run and I thought maybe it wasn't reading the imports on that dependency.

a = Analysis(['run_dashboard.py'],
             pathex=[('C:\\Users\\Andres\\OneDrive\\Documents\\Automation\\dashboard_tool_v2.0'),
             ('C:\\users\\Andres\\anaconda3\\lib\\site-packages')],
             binaries=[],
             datas=added_data,
             hiddenimports=['numpy','os'],
             hookspath=[],
             hooksconfig={},
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)

Any idea why it still wont run? it will simply open the python terminal and then close down after a few seconds. Also it might be noteworthy to say I tried to install with --onefile as I have a few .csv files that I want packaged together but then read that this might be an issue so I switched over to --onedir to no avail.
