Indesign Explorer File Icon MISSING

Hi All, I'm on a new machine and recently installed CC. The problem is Windows Explorer any indesign.indd file is missing the Indesign Icon, instead showing a generic white document. Files for all the other Adobe apps are fine. I've tried:

1. Re-associating .indd files with something else and then back to InDesign
2. Uninstall / reinstall InDesign
3. Delete the windows icon cache "C:\Users\username\AppData\Local\IconCache.db"
4. Renaming "C:\Program Files\Common Files\Adobe\Shell\CC.2022\icons.dll (& idicons.dll) to icons.dll.bak etc. But can't seem to find an alternative version to replace them with and it didn't make any difference anyway.
   
   Any ideas? This is annoying because it makes it harder to spot when you're looking for an InDesign file.
