Hi @Navaneeth Keshavamurthy Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.
The issue could most likely be caused by some versioning conflicts in the system after the update. Try reinstalling Azure Functions Core Tools to ensure that all components are correctly installed. You can uninstall and reinstall the tools using the following commands:
npm uninstall -g azure-functions-core-tools
npm install -g azure-functions-core-tools@4 --unsafe-perm true
Close out the VS Code or the IDE you are using and relaunch it. This should resolve the issue.
