How did you install ChimeraX and which operating system are you using?

And I assume you used "yum localinstall ucsf-chimerax-1.3-1.el7.x86_64.rpm" to install it?

So my guess is that we missed a dependency, so there is a missing shared library on your system that ChimeraX needs. Please run:

ldd /usr/libexec/UCSF-ChimeraX/lib/python3.9/site-packages/PyQt5/Qt/plugins/platforms/libqxcb.so

and send me the output. That lists all of the shared libraries that the Qt xcb platform plugin needs.

Hello, I'd like to solve this. From the previous message:

"So my guess is that we missed a dependency, so there is a missing shared library on your system that ChimeraX needs. Please run:
