UVW Unwrap missing functions in menu

[romakotyara]

Hi.  I got this strange quad menu in unwrap modifier.I often use stitch button through the quadmenu and now its some error. It steel works in ~menu-tools-stitch selected~ or in command panel-stitch. Is it possible to repaire somehow?  (ver. 2022.3 installed)

Do you have Windows 11 installed? I've seen a similar behaviour where Windows 11 was setting multiple files in the 3ds Max install location (usually C:\Program Files\Autodesk\3ds Max 2022) to "Hidden". Unhiding those files fixed that issue.

Other than that it may be that your anti-virus as quarantined the files that are related to those UV functions?
