SDeck DiscoverStore crashing

[76561197964853799]

On Steam Deck > Desktop > Discover,
i can open the update window & can update fine.

But if I click any of the side categories, like
Accessibility, Accessories, Dev Tools, Education, Games etc
Discover will just freeze & need to be closed.
So I cannot browse the Discover store.

Is there a temp file I need to delete to allow normal browsing?
Way to refresh it without uninstalling (as it comes preinstalled?
