Bug Updating Addressables 1.19.19 to 1.21.12 broke all addressable groups in project, how to resolve?

IT seems nearly every time I decide to update the addressables package something breaks.

What is the correct way to update? I checked the Addressables manual but don't see an upgrade guide.

 

I reverted all my addressable asset groups as they got updated via 1.21.12 and that fixed it when I rolled back to 1.19.19

This same issue has happened many many times before when updating the Addressables package where I have to re-create all my groups again.

 

My addressables got broken after upgrading from 1.21.10 to 1.21.12

 

That's the list of things that broke for me:

Just a variety of problems with 21.12, but thankfully rolling back to 21.10 fixes them

 

It may be too late but I just got the same issue after updating to Unity 2022 LTS (addressable package 1.19.19 -> 1.21.20). The addressable group windows was inviting me to create a brand new addressable asset settings file, which was super bad. Most addressable assets were broken. After trying a few things, I've found a fix.

In the project view, go to Packages. Find the Addressables folder, right-click and select Reimport. Wait a few seconds and voilà.

Also note that I had a similar weird error when I updated TextMeshPro package to the latest version. Almost everything worked except the TextMeshPro Input component... I reverted to my previous working version. But NOW after find the fix above, I did the same Reimport action and it also fixed it!

@pillakirsten fyi, there is something bad under the hood where updating a package doesn't trigger a clean reimport of that thing + dependencies.
