Hi Shafayat Syed - Thanks for reaching out.
From the first part, you are using a build in role for blob services while you are connecting to a file share endpoint. Moreover, you are further using access keys which is superlative access further.
From the Networking configuration, it goes with trusted services if you are using MI.
As a quick isolation, I would suggest you to try selecting configuration via All Networks and test the same. If that works, there is a blocker on the networking level.
Please let us know if you have any further queries. I’m happy to assist you further.
