Opening the Developer Console with CMD+SHIFT+I and looking for red text might help you further. Try deactivating plugins with names coming up in red text there.
Also, just a hunch: do you have Settings Search plugin on?
I’ve deactivated it and I do similar janitor jobs every month or so and after plugin updates (I roll them back to earlier versions when I feel something’s off – force of habit with me now).
Oh, these are general observations for PC – just seeing now it’s an iOS thread (no dev console there).
Anyways… You can do checks on PC and only use on mobile those that are working well on PC.
Good luck
