Bug Combase crashing editor.

Combase is constantly crashing the editor. I've put in two bug reports that were closed instantly. I've searched everywhere and can't find anything on this. Support stated: "The issue is related to the ComBase, which is a 3rd party package. Currently, Unity does not support 3rd party packages, thus, we recommend contacting the developer of that package for further assistance".
Previously, I had been told by support to upgrade my Unity version, which I did.

I cannot find anything on this. Log states "Got a UNKNOWN while executing native code."
The editor crashes when dragging and dropping things in general.

Edit: I do not have any ComBase package. If they're saying combase.dll is crashing Unity I don't understand.

 

Have you contacted the Combase developers for support?
I don‘t even know what Combase is, never heard of that before. Google brings up a cash register system and a microbial database.

 

Nope, I don't know what Combase is either yet. It's what support said and I see it in the log but I can't find any package.

 

Could you post your editor.log after such a crash? Hopefully the log contains some clues.

 

hang on, you dont know what it is? well, its not something ive seen either, so, its not a default part of unity.. so, somewhere, something you did must have installed it..

 

The editor crash log got wiped on restart with temp files, when it happens again I'm going to save a copy and upload it.
QA told me "The issue is related to the ComBase, which is a 3rd party package". Seeing it in the log makes sense if it's part of any GUI app, but I searched for packages that might use that name and can't find any. Makes me think there's something wrong with my graphics if that's the case. It's IN-53292. In my reports I stated the editor crashed when drag and dropping prefabs from the resource folder or in the hierarchy. Not always, but when it happens it'll happen back-to-back maybe 2-3 times on restarting Unity.
