If repair doesn't work - Reset - You may lose some data in Edge including browsing history, cookies and settings but favorites may not get lost. You are recommended to take a backup of your favorites before resetting (Open Edge > Click the 3 dots in top right corner > Settings > General > Import or export > Export to file)
Do let me know if you have any more question or require further help
