Hi Sujuitha. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.
See if you can System Restore to a point before the problem started:

System Restore is your first line of defense and can take you back to a point before a problem began like a time machine. If it doesn't help then you can undo it. Read about it first in the tutorial above and then try restoring to just before this started. If System Restore is not enabled on C drive do that now so it's available in the future.
If the problem repeats or System Restore doesn't work then check which Windows Updates were installed at Settings > Update & Security > Windows Updates > Update History, uninstall them there or System Restore again, then immediately check for and block the Updates with the Hide Updates tool explained here:

I'll give you everything possible to fix Edge so something should work:
1) If possible back up your Favorites first in Edge Hub (three dots top right of browser) > Favorites > Manage Favorites > Export to file:

If you can't open Edge but another browser will open, then go into it's Settings to try to "Import from another Browser" your Edge Favorites so they are at least backed up.
2) You can reset new Edge in Edge Settings > Reset Settings. If you can't open Edge then go into Windows Settings > Apps > Apps & Features > Microsoft Edge > Modify > Repair.
3) You can also try the repairs here:
