Rule Editor error

    Rule Editor error

    as I was building a Palo application,
    abruptly I got the the rule editor screen, shown in the annex file.
    I was not able to go on in the application devilment.

    The same screen showed as I opened other Palo applications.

    I will be very grateful if you cold help me to solve this issue

    Thank you very much
