SBMainWorkspace - The request was denied by service delegate

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)
  • Delete project & re clone it
  • 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
  • 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 Mac mini M2

Here’s the full error log:

Update

I have try with another Xcode version (14.3.1) without success, the same error occur. Work perfectly on my personal phone..

I investigate log with this command:

xcrun simctl spawn booted log show --info --debug --predicate 'processImagePath contains "CoreSimulatorBridge"'

I found a lot of strange log which said "Bootstraping failed" but it's to deep for me to understand. I'll give you more log details if you ask for.

I have been trying the above steps and formatting my complete system again for the past 24 hours.
What finally worked for me was the step I was trying to avoid.
Install rosetta running this command on the Terminal:
softwareupdate --install-rosetta
