I have a zar file from my colleague creating with a newer version of Zemax. I have no problem opening other files from him.
But when I tried to extract a particular ZAR, it keeps crashing and quit Zemax automatically.  The zar seems to be successfully extracted, generating lens file, session file and CFG file, together with ABG_DATA, COATINGS, GLASSCAT, Profiles folders (in the same folder as the extracted files though, shouldn’t it be placed in the Zemax folder instead?)

Tried to open the extracted lens file, won’t even open, Zemax will quit instantaneously.
I am currently running the Zemax on a virtual machine on AWS.
Anyone met similar issue before? What could be wrong?

Thanks very much.
