Hi fusion - just to be clear - there are 2 parts to the installation of the new version. 
First, you need to download the Nov-21 version installer from here:
 http://moi3d.com/beta.htm
After you install that Nov-21 version, then actually your .skp export problem should be solved when running that new version.
 
Note - the new version is  NOV-21 , you probably are currently running the older  SEP-21 version which has the bug in it.
 
Then to make the Nov-21 version work better, it is good to apply the patch to it because that will fix a problem with the Mirror command.
 
But if you only applied the patch to your previous Sep-21 old beta install, then that will not solve the problem, you need to install the Nov-21 version to get the SKP fix part.
 
Please let me know if you did install the full Nov-21 version and still see this same problem.   From your message it sounded like you only tried applying the patch and did not get the full install.
