Hello, I think your Qt installation may be interfering with ChimeraX. You should not have to install Qt separately to run ChimeraX, so you might try uninstalling both Qt and ChimeraX, then reinstalling either from the installer you have or a newer release candidate. Please report back whether this works, if it doesn’t, we’ll proceed from there. — Zach
