AWS Toolkit: Using non-default aws profile causes remote extension host to crash

[Tiffceet]

Problem

When using AWS toolkit, having default credentials in %userprofile%\.aws\config and %userprofile%\.aws\credentials, AWS Toolkit automatically connects.

However, when switching to non default profiles with the same credentials, aws toolkit extension will keep crashing extension host until it is disabled

Note that in my setup, my credentials include aws_access_key_id aws_secret_access_key aws_session_token

Steps to reproduce the issue

1. Setup aws credentials with aws configure
2. Make a copy of the profile in ~/.aws/profile and ~/.aws/credentials but under different name
3. Open the extension > Select a connection...
4. Select the duplicated profile

5. Extension host crashed

Expected behavior

Able to switch between profile normally
