Problem

When trying to run Design Checker Build Checks in SOLIDWORKS 2023 and newer, some users are presented with the Server Busy error: "This action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy program and correct the program". Clicking the retry button does not yield any results for this error message, and the Switch To option will cause the same error message. All the options on the Welcome Dialog Box are inaccessible, and the program is unusable.
 

This error may also present itself with the script error "An error has occurred in the script on this page" with the error description "ActiveX component can't create object: DsgnChkBuilderLib.DsgnChkBuilder.2023". Choosing to continue running scripts on the page will either cause the error to reappear or repeat the original script error message. 

This issue is a documented bug, SPR 1249268: Design Checker welcome screen shows Windows Security Warning.
