[BUG] WatchDog Crash when running XYZ test and with USB plugged in

[Madmatt06]

Please, before you create a new bug report, please make sure you searched in open and closed issues and couldn't find anything that matches. *Note There was another bug report that had a similar issue but it was on a older version, didn't mention anything about a USB drive seeming to cause it, and had to do with the fan testing after the XYZ testing succeeded.

Printer type - Mini+

Printer firmware version - 4.3.4

Original or Custom firmware - Original

Optional upgrades - Filament Runout Sensor

USB drive or USB/Octoprint USB drive

Describe the bug When running the XYZ test with a USB drive the screen freezes on the test screen with nothing happening and then the printer resets with a WatchDog error. I checked all the connections and everything is plugged in and telling it to home does not crash it. I was able to reproduce it multiple times in a row with the same results. However upon disconnecting the USB drive (no restart necessary) the printer no longer crashes. The only file on the USB drive is not corrupted and does print correctly.

How to reproduce Plugin USB drive (preferably with the same file using the disk image/file included) and run the XYZ test

Expected behavior Printer should perform the XYZ test without crashing.
