Some pages of Allegro PCB 17.2 is freeze under Win10 2020.

My computer was updated by Microsoft automatically last week. Before Win10 2020 was updtated , Allegro PCB was run normally. After updating, some errors was appeared.For example, The Define Grid page of Design Parameter Editor is freeze when i will want to modify Grid data value under the  circumstances which clicked Design Parameter Editor in Setup menu and clicked Setup Grids to modify grid value. In other words, when i clicked Setup menu of allegro PCB and clicked Design Parameter Editor item, in the page, i tried to modify grids value of Setup Grids page, i will get nothing on the Setup Grids page.  Setup Grids page will be freezed. And i can not close the  Setup Grids page as well as other pages. 

By contrast, if i clicked Grids item of Setup Menu of Allegro PCB , the software will run with no errors as well as modify the grid value sucessfully. 

The Second  phenomenon, the Setup text size page of Design Parameter Editor item in Setup menu was clicked and i can not be modified any value too. The cause is as same as  Setup Grids page. The allegro PCB was freeze too. 

Who know how to solve it? My Computer os is Win10 2020.
