This seems to be a general Darwin (Mac) problem. Occurs for Intel architecture too:

Also running into this on apple silicon. Were you guys able to work around it somehow?

With the fixes from @buschulte merged into develop-branch yesterday it should work now on the development branch. And therefore should be fixed at least with the next major release.
