Could not find net.minecraft:client:1.20.1

I have several projects across Forge versions. but lets stick to two versions. 1.19.2 and 1.20.1 are now throwing these 2 errors when I try to build the gradle

Im using the new gradle.properties as shown in the current Forge MDKs (and gradle wrapper, settings.gradle files etc)
All my projects were working and compiled with no problems over the last couple of days and now these errors are happening

Ive tried deleting the .gradle and build folders - FAIL
Ive invalidated the caches - FAIL
The Forge 1.19.2 MDK compiles fine (only one I tried) - SUCCESS

The runClient and build commands work through the terminal for my projects, but the gradle refresh and RunClient configurations do not (top right of the IntelliJ screen if you dont know what I mean)

Can someone please help
