Error 'SUCCEEDED(hr)'

Hi everyone!

In all the betas of 5.5 I keep getting this error:

Assertion failed on expression: 'SUCCEEDED(hr)'

I cant make a bug report because I dont know how to reproduce it. It happen randomly.
Sometimes in empty projects even before I import nothing.
Sometimes I can work fine for hours withour error and for now reason it spawn.
Sometimes it spawn has soon as I open Unity

The problem is that once it spawn, dosnt stop and spawn like 4 times for second.
I try a lot of stuff like changing scenes, change layout, etc etc. The only thing that solves it is closing and re-open Unity.

Good thing is I can save before close.

Actually using Unity 5.5.0b3 (64-bit), but happens in all the older 5.5 beta versions

 

I think most of the times it happens when I minimize the window or open something else(like the browser or vs) and when I back to Unity it start to launch that error. But sometimes also happens when I hit play, it start to spawn that error when I stop play mode. Those are the most common cases, but can happen in any momment .

The log file is right click on console > OpenEditorLog?
I'll add it next time it happens

 

I fixed it by installing unity and uninstalling unity beta. That fixed it

 

This is what it said now I enable trace logging full:

And here is the log file:

 

Done, the report number is 832245. Thanks for help, let me know if you need any info of my pc or there's any workaround for the mean time

 

I have it small in a corner:

 

Same error popped up today in 5.5.0b3, spamming console constantly, stops when starting the app. New project, on the scene just a few buttons. Opened and closed 5.4.0f3 in parallel, before it happened, may have had something to do with it (could not reproduce).
And Editor.log spams:
