pytest has been working for me forever. Today, after rebooting, it throws this error:
PS C:\> pytest

ERROR: file or directory not found: and
It doesn't matter if I run in a valid pytest framework or outside the framework. I uninstalled pytest and python and then reinstalled with the same results. I tried running "python -m pytest" and same results. I am running Windows 10, python 3.8 or 3.9. What am I missing?
Here's some additional output using the debug flag

ERROR: file or directory not found: and
The log file is pretty big so I'll go through it to see if there's anything that jumps out.
Okay, this is interesting:

What is this line doing:
perform_collect <Session empty_directory exitstatus=<ExitCode.OK: 0>
testsfailed=0 testscollected=0> ['and', 'level1'] [collection]
Maybe that's where it's getting the 'and'. This line caught my attention because I have a marker called 'level1' in one of my pytest frameworks. But I'm not in that directory so it could be unrelated.
If I switch to my macbook and run pytest in an empty directory, that line looks like:
perform_collect <Session temp exitstatus=<ExitCode.OK: 0>
testsfailed=0 testscollected=0> ['/Users/jhayden/temp'] [collection]
And that's the empty directory I ran from.
I also tried running in a venv:
