Hi @anon13318029, welcome to the Asana Community forum
I can see that you have already tried most of our troubleshooting steps listed here: Asana supported browsers and troubleshooting steps | Product guide • Asana Product Guide
In this case, i’d suggest reaching out to our Support team as they have access to additional tools that we don’t have here on the Community team to be able to look into this further for you.
You can reach our Support team by following these steps: How to contact our Support Team ✉
I hope this helps!
