I now had the second user with 26.2. complaining about a hang in my app. The hang occurs when the first AppleScript for Mail is run. Here is the relevant section from the process analysis in Activity Monitor:

+                             2443 OSACompile  (in OpenScripting) + 52  [0x1b32b30f4]
+                               2443 SecurityPolicyTestDescriptor  (in OpenScripting) + 152  [0x1b32a2284]
+                                 2443 _SecurityPolicyTest(char const*, void const*, unsigned long)  (in OpenScripting) + 332  [0x1b32a2118]
+                                   2443 InterpreterSecurity_ScanBuffer  (in libInterpreterSecurity.dylib) + 112  [0x28c149304]
+                                     2443 -[InterpreterSecurity scanData:withSourceURL:]  (in libInterpreterSecurity.dylib) + 164  [0x28c148db4]
+                                       2443 -[XProtectScan beginAnalysisWithFeedback:]  (in XprotectFramework) + 544  [0x1d35a1e58]
+                                         2443 -[XPMalwareEvaluation initWithData:assessmentClass:]  (in XprotectFramework) + 92  [0x1d359ada4]
+                                           2443 -[XPMalwareEvaluation initWithRuleString:withExtraRules:withURL:withData:withAssessmentClass:feedback:]  (in XprotectFramework) + 36  [0x1d359b2a8]

My app is correctly signed and notarised. The first user had to completely uninstall/reinstall the app and the everything worked again.

Why does this happen? How can the problem be fixed?

Exact same problem with same stack trace for our app. We create an NSAppleScript option and it is now hanging when we call executeAndReturnError or compileAndReturnError.

Some more information:

My AppleScripts usually are very simple because the app does the heavy lifting. Think getting the accounts for Mail or the account type.
I have 2 places in the app where I use AppleScript. In the Setup the users determines which email she wants to archive from Mail. And then the user can archive the emails to a database. The Setup uses the AppleScripts in a thread. Archiving is threaded, too. But the AppleScripts are run on the main thread and before threading starts. The scripts run fine on the main thread. These are the same scripts which are used in the Setup!!!
I've moved the first AppleScript to osascript and now the second script hangs which is still using NSAppleScript.

The plan for today is to move more AppleScripts to osascript.
