### Electron Version

12.0.2

### What operating system are you using?

macOS

### Operating System Version

macOS Catalina 10.15.7

### What arch are you using?

x64

### Last Known Working Electron version

_No response_

### Expected Behavior

Returning an invalid serial port ID in the callback of the `select-serial-port` event handler of `session` should not crash Electron.

### Actual Behavior

Returning an invalid serial port ID in the callback of the `select-serial-port` event handler of `session` crashes Electron with a SIGSEGV. Calling the callback with `"foo"` or any string that is clearly not a valid serial port ID is enough to trigger the bug. Valid serial port IDs and empty strings work as expected.
