Cannot create collection config.system.sessions because we already have an identically named collection

[Divyanshu_Soni]

Hello, @Konstantin_Manchev1 I ran into a similar issue and had to drop system.sessions collection from any router and let mongo recreate it after next logicalSessionRefresh. Although I had version 4.2.13. You might need to run flushRouterConfig from each router after dropping that collection or restart them one by one.
