First run seems everything was ok, but when I changed any setting (ip port name etc.)in connection tab of gui, it will crash at rerunning

Even I tried to export the reg file from other win10 computer that clinet works fine there , and inport file to this one, it not works. HKEY_CURRENT_USER\Software\WinNUT

After several times reinstall repair ,It crash yet
