Hi @ashvinimarwal, please check https://magento.stackexchange.com/a/195091/40869 and use GitHub for bug reports only. Generally such kind of error indicates invalid XML files in your code and they just needs to be fixed to correlate with XSD.

If solution didn't work for your, please ping us back and issue will be reopened for further investigation.

I'm getting a similar error after running updating M2.3.5-p1 to N2.4.0 via Composer Update
Fresh install, no extensions.

The error happens when trying to logging to the admin
(BTW, if the only error message had also included the XML filename everyone's life would have been so much easier)

1 exception(s):
Exception #0 (LogicException): Could not create an acl object: Invalid Document
Element 'resource': The attribute 'title' is required but missing.

...

BTW, the extension at fault was the Two Factor Auth
This is (my favorite) fix: bin/magento module:disable Magento_TwoFactorAuth
