Hi @bastiacelyn
Welcome to the Premiere Pro forums! We are glad to see you here. That sounds like a real problem. Can you tell me if this is happening only in Premiere? Does the space bar play/ pause the timeline, or is that also not working? When you're entering the test - where are you trying to enter it? Which panel/ workspace?
We need a few more details to help with this issue. Please see: How do I write a bug report?
I hope we can help you soon. Sorry for the frustration!
