ERROR (bellows.thread_0) [bellows.uart] CRC error in frame b'000607a1ad6cc17e' (b'6cc1' != b'f90d')

Does anyone know how to get rid of all these errors in my Home Assistant log?

Im running Home Assistant in a VirtualBox VM. I can see that some of those errors are related to the Plex integration. However, I don’t really have many options to change or select in the integration. Also, I’m not even sure if it’s related to the other CRC errors I’m getting.

PS: I am using a HUSBZB-1 USB Hub

EDIT: I just notice the line in my log below. I’m not exactly sure where to report this:

2020-07-08 19:52:44 WARNING (MainThread) [homeassistant.util.async_] Detected I/O inside the event loop. This is causing stability issues. Please report issue for plex doing I/O at homeassistant/components/plex/sensor.py, line 119: if sess.year is not None:

EDIT: I just created an issue for this:
