How to fix the error: "AppleSpell" tried to hijack endpoint "it (Apple)_OpenStep" from owner?

Solution 1:

Let’s dig into the stalls and memory errors directly as this message cleared up for me on updating the OS. Any chance you would like to make a follow up question, just link in the comments below and I’ll gladly have a look.

There are more than one libraries, and you’re calling the older one and not the newer one, so this is just a versioning issue that happens from time to time AFAIK.
