Hi Everyone, it's been a while since I resolved this issue. Turned out, I was logged into Q portal using different account than what was previously setup with access. QCLI did not have any clear identifier for me to troubleshoot quickly. I recommend you to check the account that you're logging in Q developer with. This issue can happen if you have switched between accounts like I did in my situation.

In my case, uninstall (amz q) -> restart (vs code) -> install (amz q) -> restart (vs code). This worked for me.
