Check Duplicat Bundle Dependencies "Fix Rule" operations never completes

I am trying the “Fix” step for Check Bundle Dupe Dependencies analyze rule for around 19k duplicated assets in bundles. This always gets stuck at the importing assets step. I have let it run overnight for ~9 hours but still the process won’t finish. I had to force quit and open unity. I do see that all the duplicate assets are now moved to a separate group. To counter this behavior I wrote a custom rule similar to Check Bundle Dupe Dependencies but this time instead of processing all the bundles, I forced it to fix just one bundle with one duplicated asset. I still see the same behavior where unity is stuck on importing assets step which is very annoying… Has anyone else seen this behavior with Analyze Rules. Using unity 2021.3.42f1 and addressables version 1.21.20

Apparently few assets which addressables system was trying to group contained [] in the asset name which in turn is used in it’s address path. The system is not able to recover from this error. I had to skip all the assets with [] in the name and run the Fix step for everything else.
