Interface locks up, repeated "StreamFX] Unexpected exception..." errors

Have been using OBS for 1yr+ to teach online university classes
(late 2019 Intel MacBook Pro, Big Sur 11.6.4, OBS 27.2.2)

Recently found that for my main scene collection, the OBS interface
cartwheels, with the log file filling up with StreamFX messages.
Example log file lines, plus full log attached.

> [StreamFX] Unexpected exception in function '_video_render_filter': std::exception.
> Last log entry repeated for 120 more lines

There is no crash log, as OBS doesn't crash, just takes up 200% CPU.
I can still use Touch Portal to change between some scenes, and some other
scene collections seem to be unaffected, but this main one has become unusable.
Since StreamFX seemed to be the issue, I tried to re-install it, following the
install guide, but no change...

Hoping that some knowledgeable folk here might be able to help me out.
