[MacOS] 8.xxx versions all crashing when entering text

[twisterfreak]

Since the update to 8.xxx my calibre has been crashing everytime I try to enter text in the search bar or while editing metadata.

I'm using Mac OS Sequoia. The downgraded version of 7.xxx is working fine but the newer versions are not.

That's a crash in a CA:Context thread which is a CoreAnimation thread. calibre doesnt use any such threads, so its coming from some component on your system, presumably you have something installed system wide that is causing it.

Could also be a corrupt font.
