Crash of Numbers and Pages on Big Sur

When i want to open Numbers or Pages its showing up for a second and its sending the report Numpers/Pages quit unexpectatly. I happened before the last update and after the update, i restarted, i forced to quit, i uninstalled the apps and downloaded afresh, its always the same. I followed the steps given through "go to folders, library, com.apple iwork and so on........ no change.

I am desperate-all my files for work are in numbers and pages, i need help!
