My Android Nextbook Tablet refuses to open the settings app...

[AC Question]

Every time I begin to open my Nextbook setting application, the tablet refuses and reverts back to the main interface where the apps are shown. I cannot open the settings app to review my personal and system settings anymore. The malfunction has been a problem for a while, about 4-6 months to now, can you help me fix this problem?
