SharePoint SE Aggregated newsfeed empty after installing March 2024 CU

Question

After installing the new patch for March 2024 we no longer has a working aggregated newsfeed. It's stuck on

'We're still collecting the latest news. You may see more if you try again a little later.'

The ULS logs:

Unexpected error occurred in method 'BulkGet' , usage 'FeedCache' - Exception 'System.InvalidCastException: Unable to cast object of type 'System.Collections.Generic.List1[System.Collections.Generic.KeyValuePair2[System.String,System.Object]]' to type 'System.Collections.Generic.IEnumerable1[System.Collections.Generic.KeyValuePair2[System.String,System.Byte[]]]'. at Microsoft.Office.Server.DistributedCaching.SPDistributedCache.BulkGetT'.

Unexpected exception in FeedCacheService.GetConsolidatedFeed: Unable to cast object of type 'System.Collections.Generic.List1[System.Collections.Generic.KeyValuePair2[System.String,System.Object]]' to type 'System.Collections.Generic.IEnumerable1[System.Collections.Generic.KeyValuePair2[System.String,System.Byte[]]]'..:

I've restarted, and recreated the distributed cache services. Recreated the user profile application and the other usual suspects.

Does anybody have any suggestions?
