SimLink hangs X-Plane on Mac OS 11.3.1 Big Sur

the simlink-Plugin stops X-Plane from starting after Updating from Mac Os 11.3 to 11.3.1. When moving NavigraphSimlink_64.xpl from the plugins-Folder to somewhere else, X-Plane starts without any problems. This is on Apple Silicon M1 Macbook Pro, X-Plane 11.53.

Is this a known issue?

Thank you,
