not sure how to proceed now, i see a lot of this in the log

v16 was same, went back to v12 and its working again.. will be very wary of upgrading now

 

Yeah, I too have bunch of:

Code (CSharp):

1. InvalidOperationException: EnsureRunningOnMainThread can only be called from the main thread
2. UnityEngine.Object.EnsureRunningOnMainThread () (at <0d01204b437e47c1a78b600b597a89f4>:0)
3. UnityEngine.Object.GetInstanceID () (at <0d01204b437e47c1a78b600b597a89f4>:0)

What the hell this errors means?

 

does it crash unity for you or not?

 

No, it's just spam errors, nothing else. But lots of them, I don't know the reason.

 

I have them too

Almost three week since 2020.1.0 Alpha 17 has been released, when will we get Alpha 18?

 

I assume a19 will be released. Maybe beta soon.

 

After holidays

 

I got 2019.3 should I jump into 2020, or don't risk it.

 

Not right now, just for testing yes, but keep your project on 2019
