Unity hangs at end of building addressable catalog

Hello, first time posting so be gentle. We're currently having some trouble with the addressables system after upgrading to 1.6 (Unity 2019.2.10). Our addressables that were working before are now having ChainOperation failed because dependent operation failed. These errors weren't happening before and we are unsure of how to find the dependent operation. There is also an error where Unity freezes and just slowly leaks memory at the end of building the addressables catalog. We have to terminate in task manager and reopen the project. I am also unsure if the catalog is even being properly built during this memory leak. Any clues would be appreciated!

 

We resolved this, we had thought the addressables had crashed, but they take like an hour to build.
