Same problem on Ubuntu 21.04. started gnome-font-viewer from terminal the window opens but is unresponsive. closing it I have the crash and a message: corrado@corrado-n8-hh-0101:~$ gnome-font-viewer
(gnome-font-viewer:4532): Gdk-ERROR **: 08:22:36.317: The program 'gnome-font-viewer' received an X Window System error. This probably reflects a bug in the program. The error was 'BadIDChoice (invalid resource ID chosen for this connection)'. (Details: serial 1502 error_code 14 request_code 130 (MIT-SHM) minor_code 5) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

Application will crash if there is an attempt to close it or scroll through fonts. On one occasion my laptop was rendered unusable when Firefox was launched while trying to report the crash to Launchpad. After the bug report has been sent gnome-font-viewer will freeze when automatically restarted. No fonts are displayed. Work around ----------- gnome-font-viewer appears to start correctly when started from the command line of my Ubuntu 20.04 installation. Then subsequent attempts to start the program succeed when started from the dock or the Application Overview. I have found that this work around wasn't necessary when using Xubuntu 20.04.
