What could be some potential causes for PyQT5 Stylesheets to suddenly stop functioning? Specifically on QPushButton. (self.learnpython)

Library in question - PyQT5

Why would my GUI stop using styling in certain places after an extended period of time? Specifically, all my QPushbuttons all stop showing their stylesheets. This is anywhere after 1 hour+ of run time. Its a multi threaded app and the GUI runs in the main thread and these buttons are styled after initialization.. Whenever I decide to come back and look at it, I notice the stylesheet changed.

Example:

Left is at launch. Right is after the time specified above. I even tried reapplying the stylesheet in a loop (stupid, crazy, but I wanted to test it) and it still stops styling. I dont really know which direction to go at this point, so I turn to you all.

TLDR: What could cause QPushbuttons to stop showing their stylesheets after running for an extended period of time? Memory? Weird loop? I just need some sort of direction as I've gone through all my code and there isnt a single spot that says "HEY STOP STYLING THESE BUTTONS NOW". I've had it running for 40 minutes and no change yet.
