Importing (Iteration x) infinite loop

I'm currently trying to get IAP up and running on my game, but when I try to import the IAP package the installer seems to get stuck in an infinite loop of iteration. The first step of the installer is fine and second step seems to be, but then as shown below the installer gets stuck at the stage Plugins\UnityPurchasing\Bin\Facebook\live\FacebookStore.dll

Has anyone ever encoutered this issue and know of a way to fix it?

I can end the loop by ending task and then have to delete the UnityPurchasing folder to get back into my project since the iteration loop starts again on load.

I have tried importing the package both from services and the unity asset store.

Thanks in advance

 

Just to add on in case it makes a difference, i have tried on a blank project and i get exactly the same issue

 

Sorry Jeff, think our posts overlapped. I am 2019.3.0a2 and empty/new projects don't make a difference unfortunately

 

ah, probably should've tried that before posting, but anyway thank you very much for the quick reply - appreciated!

 

At our company, we have recently upgraded to the release version of 2019.3 and several colleagues of mine are still having this issue. Yet, I can find no reference to it, except this forum post. Anyone else having issues with this?

Our current "solution" is to completely delete the Library cache and all generated files, however the problem comes back after switching to a new scene in the project.

 

Myself and others had the issue but somehow by repeatedly deleting the Library cache it seems to have stabilized (for now). Yet another, the issue suddenly appeared and did not go away.

Eventually, we managed to 'fix' the issue by reverting the AssetPipeline to V1 (Deprecated).
The version we are running is Unity 2019.3.0f6
Our projects are pretty complex, so we do not have a clear idea on how to start reproducing it (i.e. finding the minimal case). Thus we have not attempted recreating it with a new project.

 

Im experiencing an endless import cycle on multiple projects using Unity 2019.3.1f1, but its seems it's more caused by Shader Graph 7.2.1. When I revert back to Shader Graph 7.1.8, all is fine again.
