SIGSEVs when trying to use Serenade on macOS Big Sur

[samueldemoura]

Hello! I just installed Serenade and was trying to make it through the Python tutorial, but it keeps consistently crashing after one or two commands. Another interesting thing is that after the crash, my input method is switched for some reason (as in: switches from English to Japanese if I have these configured, for example).

I'm on Big Sur, 11.6. Backtrace of the main thread looks like this:

Which seems to point to this line:

driver/src/mac.cpp

Line 751 in f22d3ec

reinterpret_cast<const UCKeyboardLayout*>(CFDataGetBytePtr(layoutData));

Let me know if I can provide any more information to help with debugging.
