Launching error of S1 Mission program

When trying to launch the Sentinel-1 Mission program in PolSARPro v6.0.3 Biomass, I encountered an error message as follows:

can’t read “widget(PSPEDUC1)”: no such element in array
can’t read “widget(PSPEDUC1)”: no such element in array
while executing
“$widget(PSPEDUC1) configure -state disable”
invoked from within
“.top3.fra66.cpd69.but93 invoke”
(“uplevel” body line 1)
invoked from within
“uplevel #0 [list $w invoke]”
(procedure “tk::ButtonUp” line 24)
invoked from within
“tk::ButtonUp .top3.fra66.cpd69.but93”
(command bound to event)

and then the program panel is not able to use.

I wonder if it’s a problem of my TCK software or the problem of PolSARPro itself. Additionally, the PolSARpro Bio program works normally.

The runtime information as follows,
OS: Windows 10
TCL: tcl-8.6.11
