For anyone looking at this its the same problem as described and fixed here #46450 but with a different character

Thanks @brianteeman

The fix in #46450 is only for email form field.
My issue is url form field related.

yes I know - i'm just pointing out a similar problem also caused by the IDNA update for developers to reference when fixing this

It's ok!

@luX0r-reload I will work on this bug,
can you tell the exact URL that causes the crash ?
I am getting no errors with the URL: https://www.example.com/foo'bar
but getting a fatal error for the URL: https://www.exa'mple.com/foobar
If you can confirm this, the expected result for a fix will be a error message being shown instead of a fatal error ( not no errors )

@hiteshm0
This crash:

https://www.exa'mple.com/foobar

This not:
https://www.example.com/foo'bar

I agree with what you wrote.

@luX0r-reload can you please take a look at 47557, and let me know if that fixes the bug?
Thank You

Yes, with the fix, it saves the URL and doesn't crash.
