[Bug]: TypeError: : Cannot read properties of undefined (reading 'value') in create-class-features-plugin #16752
Description
💻
- Would you like to work on a fix?
How are you using Babel?
babel-loader (webpack)
Input code
Code generating the error is:
Configuration file name
No response
Configuration
I'm assuming the stack trace will be enough. I'll amend to add the full config if needed.
Current and expected behavior
When @babel/helper-create-class-features-plugin is upgraded from 7.24.8 to 7.25.0, we get the following error when transpiling the linked file above:

Babel core 7.25, node v20, yarn 4.4
Possible solution
No response
Additional context
Pull request with failing CI is home-assistant/frontend#21734. Note the CI passes prior to this so there's just the Babel changes in the lock file to blame.
