Teams Desktop App not loading Lists tab in Guest account

In the Teams Desktop App, guest account users can't open the Lists app tab.
When the guest user opens the tab, after 20-30 seconds, the message "There was a problem reaching this app" is displayed.

The same error does not occur in the Teams web app.

I tried the following steps, but the error didn't go away.

  • Sign out -> Sign in

  • Reinstall Teams desktop app

  • Clear Teams cache

Can you tell me how to solve it?

Hi @KatzN-0195 ,

Does this issue persist all the time?

Can you reproduce this issue on another device?

Can guest user access to other app tabs (Planner and so on)?

To troubleshoot this issue, we recommend you go to SharePoint Online Admin Center and check your site permissions of content sharing and content sharing policy like the following pictures:

@JimmyYang-MSFT

Thank you for your detailed answer.

Does this issue persist all the time?

Yes

Can you reproduce this issue on another device?

Yes

Can guest user access to other app tabs (Planner and so on)?

I'm not sure, because there is the only Lists tab.

The target Teams is in the our customer's Office 365 tenat.
So I can't chech SharePoint Admin center...

We (my company menbers) can open the Lists tab with Teams Web app, but can't with Desktop app.
Is it due to the SharePoint settings?

For me this issue is not resolved after changing the permissions as suggested here. For complete outline of the issue please see:
