Hi Mai,

The information from your log doesn't make much sense. It is reporting that your version is 1.10.1, but the error is showing code that does not exist in 1.10.1 and was only introduced in 1.11 and later. Did you install a newer ChimeraX on top of an older one? Maybe you should remove ChimeraX entirely and reinstall.
