Version 1.3.8 is not working

Hi,
My current version and the previous doesn’t work right now, but it used to work.
Open the WooCommerce PostFinance Checkout settings and save it, I get folloing message.

Could not update payment method configuration.
Could not install webhooks, please check if the feature is active in your space.
Could not update the manual task list.
Please check your credentials and grant the application user the necessary rights (Account Admin) for your space.

I turned debug on:
