This issue was raised before but was already resolved by our engineers.
We can do the basic troubleshooting steps to refresh your browser. To do this, please sign in to QuickBooks using a private browser. This step disables its extensions and stops the cache from saving your browsing history.
If there's no error, you can go back to your regular browser and clear its cache. If it's still there, please try other browsers to see if we get the same thing.
If nothing works, please contact our Support team, so they can get your account details and revisit the case. Only that team has access to accounts.
Feel free to share an update after doing the steps above.
