Roblox links won't open with Microsoft Roblox

It seems like your system is still associating the Roblox player's app with the links instead of the Microsoft Roblox app. Here are a few things you can try to resolve the issue:

1- Reset the default app settings: Go to Windows Settings > Apps > Default apps > Reset to default. This will reset the default app settings for all file types and protocols, including Roblox links. After doing this, try opening the Roblox link again and see if it opens with the Microsoft Roblox app.

2- Set the default app for Roblox links: Go to Windows Settings > Apps > Default apps > Choose default apps by protocol. Look for "Roblox-player" in the list and click on it. Then select "Microsoft Roblox" as the default app for this protocol.

3- Uninstall both apps and reinstall Microsoft Roblox: Uninstall both the Roblox player's app and the Microsoft Roblox app. Then download and reinstall the Microsoft Roblox app from the Microsoft Store. After doing this, try opening the Roblox link again and see if it opens with the Microsoft Roblox app.

Hope this can help you solving the issue.
