You have a bad install

```auto

Error: System.IO.FileNotFoundException: Could not load file or assembly 'ObjectDumping, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5b84c0cf1ad6e363' or one of its dependencies.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

```

This happens if you try to upgrade from a version prior to 2.6.3 directly without first uninstalling the old version: [MCEBuddy Monitor Thread Crashed after first item is processed in the queue v2.6.2 - #4 by Goose](https://discussion.mcebuddy2x.com/t/mcebuddy-monitor-thread-crashed-after-first-item-is-processed-in-the-queue-v2-6-2/5320/4)

Uninstall and reinstall MCEBuddy and it should be fine.
