Thunderbird stopped working on my regular computer and disappeared. When I try to bring it up get a very long error message starting, "The procedure entry point ???0LockedMarkerTypeFunctions. . . . When I hit "OK," next screen says, "Couldn't load XPCOM." On that computer, I'm running Windows 11. I apologize for any errors in typing; I have limited use of my hands. Thank you.
