Go it working again.
Forge -> Select your game -> 3 dots on the right -> Profile Options:
I've raised the modloader version here to 53.0.11
Disabled all mods (libIPN, Inventory Profiles Next, JourneyMap, Kotlin for Forge)
Noticed its working again.
Switched on 1 mod at a time until on were on.
Bug's gone.
Hope it helps.
