RuntimeError: Invalid PM2.5 header

Following this guide https://learn.adafruit.com/pm25-air-quality-sensor/python-and-circuitpython with minor adjustments I keep running into this error...
"Traceback (most recent call last):
File "code.py", line 190, in
File "/lib/adafruit_pm25/__init__.py", line 83, in read
RuntimeError: Invalid PM2.5 header"

I am using a Teensy4.1 instead of the Feather to control the WiFi Module, Temp sensor, and PM25 Sensor. I am using the UART connection method. What will happen is it will run for a random amount of time, sometimes 5 hours, sometimes 30 minutes before running into this error. I'm unsure how to fix the problem without just looping a reset but that does not solve the problem.

Thanks,

Start with code.py around line 190 and lib/adafruit_pm25/__init__.py around line 83, then compare the UART setup with the linked PM2.5 guide and the Teensy4.1 configuration. Reproduce the intermittent failure over time and identify why the PM2.5 header becomes invalid; done means the sensor can run without this RuntimeError.
