Entra ID login fails – popup replaced by new tab with error

We are using Robopack to deploy software in our customer tenants via Microsoft Intune.
Login is performed using Entra ID credentials via:
https://app.robopack.com

Normally, when clicking “Log in with Entra ID”, a popup window opens for authentication.

Current behavior:
Instead of opening a popup, physonics opens a new browser tab.
The Entra ID login process starts in a new tab, but after authentication an error is displayed.

Expected behavior:
A popup window should open and complete the Entra ID authentication successfully, as in the normal browser.

Steps to reproduce:

1. Go to https://app.robopack.com

2. Click “Log in with Entra ID”

3. A new tab opens instead of a popup

4. Login completes, but an error is shown afterward

Question / Request:
Is it possible allow popups?
