Updating to 2.3.0.3 (Stable) breaks all connections

Just updated Duplicati to 2.3.0.3 stable.

I use it in portable mode: start Duplicati.GUI.TrayIcon.exe --portable-mode)

Didn’t change anything in config, but now all S3 and Storj connections are broken.
Just clicking “Test Now” for S3 (amazon aws) returns this error:

Test connection failed

Error
 listing content: Failed to resolve AWS credentials. The credential 
providers used to search for credentials returned the following errors:

Exception 1 of 4: The environment variables 
AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY/AWS_SESSION_TOKEN were not set 
with AWS credentials.

Exception 2 of 4: The webIdentityTokenFile must be an absolute path. 
(Parameter 'webIdentityTokenFile')

Exception 3 of 4: Unable to find the "default" profile.

Exception 4 of 4: Failed to connect to EC2 instance metadata to retrieve
 credentials: Unable to get IAM security credentials from EC2 Instance 
Metadata Service..

My s3 connection in the config looks:
"TargetURL": "s3s://mys3bak/BAK?``s3-server-name=s3.amazonaws.com``&s3-location-constraint=EU&s3-storage-class=&s3-client=aws&auth-username=***&auth-password=***",

Also It reintroduced the old STORJ bug where Access Grant only works in the old UI.

In the NEW UI it returns error:

NULL: api_key
	main.uplink_config_request_access_with_passphrase:26
	_cgoexp_128b453d6672_uplink_config_request_access_with_passphrase:738
	runtime.cgocallbackg1:446
	runtime.cgocallbackg:350
	runtime.cgocallback:1084

Access Grant is selected, but it the new UI it tries to use API. This bug was reported and fixed in previous version:
