Suddenly I am not able to login into my dev environment getting this new kind of error - please let me know if anyone is familiar with this issue. Cannot Load Navigation interface Defination . from same console I am able to login into PROD instance.
If the soft clear doesn't work try the hard cache clear. Please see the doc below for the steps:
Hello @mohammedo844240 ,
Go to File and Clear local cache and check if this fixes the issue.
