BLE extension emulator runtime error

runtime error using emulator when BLE extension added. This test project has NO blocks, just the BLE Extension as non-visible component in one screen. Emulator runs normally on all other projects with no BLE extension using current version of AICompanion (edu.mit.appinventor.ble-20230728.aix). MIT App Inventor Build = September 14 2023 Version: nb194c
