Windows Search corrupt catalog & wrong permissions

Hi, I just did a fresh upgrade install and I already have 2 errors in the Event log --> Application section.

Error 1: (2019-01-12T17:13:36 AM) (Source: Windows Search Service) (User: )Description: The Windows Search Service is being stopped because there is a problem with the indexer: The catalog is corrupt.Details:The content index catalog is corrupt. 0xc0041801 (0xc0041801)

Error 2: (2019-01-12T17:13:36 AM) (Source: Windows Search Service) (User: )Description: The search service has detected corrupted data files in the index {id=4810 - base\appmodel\search\search\ytrip\common\util\jetutil.cpp (609)}. The service will attempt to automatically correct this problem by rebuilding the index.The data is invalid. 0x8007000d (0x8007000d)

Error 3: I ran the WIndows Search Troubleshooter as Admin, selected all options and the tool did detect an error with Permissions, yet when the scan was completed the error was not fixed.

I can add more details from the Event log & Troubleshooter but it would clog up my first post where I want to keep things compact. Having said that, I now will list the things I've done so far:
- sfc scannow
- dism /Restore Health
- check the WSearch Service, which is running & set to delayed start
- and finally I'm rebuilding the Index thru Control Panel --> Indexing Options --> Advanced

The Index is being rebuild as I typ here, so I'll just add more details from the Event log in a subsequent post and then wait to see if re-indexing fixed my issues...

Error 3 (English translation below):

Search Troubleshooter Onjuiste machtigingen voor Windows Search-mappen

Status: Niet opgelost Als de machtigingen in de Windows Search-gegevensmappen verkeerd zijn ingesteld, is de zoekindex van de computer mogelijk niet toegankelijk of kan deze niet worden bijgewerkt. Dit kan resulteren in trage zoekopdrachten of onvolledige zoekresultaten. ----------------------------------------------------------------------------- Incorrect permissions for Windows Search folders Status: Not resolved If the permissions in the Windows Search data folders are set incorrectly, the search index of the computer may not be accessible or can not be updated. This can result in slow searches or incomplete search results. ----------------------------------------------------------------------------- I just rebuilded the index, rebooted, ran the Troubleshooter again, with the same result tho; Problem not solved! Don't know what to do next...
