Hi, I have the same problem, but every software is up-to-date. This started after upgrading to Catalina. On start-up, Logic crashes after a few seconds, while loading the EZDrummer plugin.
Here is the crash report header with the relevant infos on versions (macOS 10.15, Logic Pro X 10.4.7, EZDrummer 2.1.8):
