Page editor frozen

Page editor frozen

Hello community, I hope you are very well. I´m having a problem a problem with my apps. I have a form with a few records, and I am trying to make a page with some indicators, so I went to the page editor, i took the "New Employees this month" Panel from the left options, then I clicked in design and I tried to change form "static text" to “count”, then I selected my form and in that moment the editor gets frozen. I must close chrome because all the options become disable. I tried in a different app, i tried with another form, gauges, charts, maximum instead count, sum, edge instead chrome. I tried everything but the editor always get frozen. Have any of you had this problem before? If you know how to solve this problem, please help me.

 Thanks my friends, and so sorry for my English, I know I am not good on it. 

 I attached two photos of the problem.
