Test Automation in Build Process Automation is hanging

[nknight]

I am on Learning Journey "Utilize SAP Build for Low-Code/No-Code Applications and Automations for Citizen Developers". I am in unit two in the section "Boosting Business Process with Automation". I have created my automation following all steps and it looks as follows (exactly the same as shown in the training):

When I get to the step of "Testing the automation" it does nothing as per below. Just sits there forever:

I cannot see any errors as such, it just doesn't load the popup. Has anyone else encountered this or knows what the problem could be?

Regards
