Inventory - Manage All Inventory Search Button no longer working properly!

Since Monday morning the search button is no longer working properly on my user account only, none of the other user accounts have thankfully been affected.

I have tried clearing cache, cookies, and using other browsers, even devices but still, the same issue persists. If I try searching it will try and load but fails. Any idea how to fix this, please? Seller support could not help either.

I feel I have no choice but to delete the user and create a new user as new again to hopefully fix.
