 With the latest torbrowser, I get an instant crash as soon as it starts.

 There is nothing in the log.


 I did the usual uninstall / wipe data files / reinstall / reboot / etc.

 When I start the browser, I get this error in the console, from
 EmojiFunctionRowIM_Extension:

 <NSXPCConnection: 0x60c000105850> connection from pid 5063: Exception
 caught during decoding of received message, dropping incoming message.
 Exception: Exception while decoding argument 0 (#2 of invocation):

 argument 3: {@?} 0x0 (block)

 Exception: decodeObjectForKey: class "TitlebarAndBackgroundColor" not
 loaded or does not exist

 I do not know if this is what is bringing the browser down, but I only see
 that error when I try to launch the browser.

 I tried to disable the emoji touchbar service, which created some
 unrelated odd problems, but that didn't change anything.
