Files not saving or exporting. Rhino R7 + 8 using win 11

weird case come thru on tech recently and wanted to share the fix-

The symptom was rhino would fail to save or export a file to a typical location that a user would expect. (say the C drive.)

error thrown looks like this- (specific path redacted for user privacy)

there is a setting in win 11 that you may need to fiddle-

see this page

you may need to go thru the steps outlined and also add rhino 7 and 8 to the safe list so you can save again.

@Japhy was the one who helped sniff out the fix. Kudos!
