Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.1 and earlier, you may see this internal error when the Tcl command [get_all_assignment_names -module <map|fit|tan|asm|eda|drc|generic>] is used in the Tcl console GUI.
To work around this problem in the Intel® Quartus® Prime Pro Edition Software version 22.1, run the Tcl command in the Intel® Quartus® shell quartus_sh.
This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 22.2.
