Hello here ! I’m encountering a bug when launching an app on the simulator which is: The request was denied by service delegate (SBMainWorkspace). I know that there are some topic about this error, but any solution works for me. 
This is what I have already try: Clean Derived data + project Reset simulator Check empty environment variables (for all target + pod) Update Xcode Reinstall Xcode Restart the Mac (multiple time) Check for Mach-O Type build settings is set to executable Try on different simulators (iPhone 15, 15 Pro & 15 Plus) Try on different iOS versions (16, 17 & 17.0.1) Desintegrate + reinstall pod Kill simulators, restart Xcode Clear Xcode cache from storage settings Try on different Xcode versions (15, 15.0.1, 14.3.1) Many of the things mentioned above at the same time Note that this bug only occurs on one specific project. I can run any other project on simulator normally. The same project run also normally on other Mac. Here’s my configuration: Xcode 15.0.1 (15A507) MacOS Sonoma 14.0 (23A344) Here’s the full error log: Simulator device returned an error for the requested operation.
