AWS command hanging after assume when running on WSL

I've just installed granted on WSL Ubuntu and seeing some weird behavior with aws command hanging after I've assumed into a role.

Running with the --exec option works.

assume "my_role" --exec 'aws s3 ls'

but

assume "my_role"
aws s3 ls

just hangs and never returns.

I can see two processes running related to this

alastair    1631    1137  0 14:22 pts/0    00:00:00 aws s3 ls
alastair    1636    1631  0 14:22 pts/0    00:00:00 granted credential-process --profile my_role

any idea what is going wrong?

This is in the log file
