Since the 1.18 update, multiple times (maybe about 6) I have had an issue where I'm unable to move items out of their item slot in my inventory. It's not always the same slot, sometimes it's even in the hotbar. I can't click and drag that stack of items. I can't Quick Move the stack. So far, I have only had this happen with stacks of Bones, but that may be a coincidence. It usually only lasts a couple minutes. If I pick up more of that item or manage to place one in an itemframe or just move some other items around, sometimes it seems to help. Other inventory slots seem to be unaffected.
