Asana crashes when pasting in bullet list to task description

Welcome to the Asana Community Forum @Johanna_Batterton :wave:
Sorry to hear that you are facing problems.

Have you checked the troubleshooting steps already?
A lot of times this does the trick.

In case this does not help I recommend reaching out to Asana support and they can look into this further. When you email them it would be great if you can attach a video of the problem as well.
