Now when I npm start the project it gives me an error
An unhandled exception occurred: Class extends value undefined is not a constructor or
null
I searched for the same error and their solutions did not work for me Because they did not encounter this error to update their Angular project And I checked all my components and everything is working properly
I would be very grateful if you could help me with this problem
