[Eric Pettersen]

The Chinese translates to "The specified module could not be found"

[Zach Pearson]

There's nothing we can do about this. It's probably aggressive antivirus software quarantining or blocking unsigned/unfamiliar .pyd and .dll files silently. The error message says "module could not be found," which is exactly what happens when an AV has silently removed or blocked a DLL.

The user could run dumpbin /dependents or Dependencies.exe on the .pyd, which would reveal which DLL is actually missing — likely either a VC++ runtime DLL or one of the ChimeraX native libs that got quarantined.

Not much we can do in code to fix this. It's an environment issue on the user's machine. Try whitelisting ChimeraX in your antivirus software's menu.
