When I created the group in the ios background and added it, xcode said it was unavailable

After the ios background creates the group and adds it to the Identifiers, an error is displayed at xcode signing. Error: An Application group with Identifier 'group.xx' is not available. Please enter a different string. Looking at Figure 1 and Figure 2, you can see that I have created in the background, but it will not succeed in XCODE. Does anyone know the reason I started to think that the account and certificate problems, but after the replacement is not successful

How to solve this problem, thank you

Me too

I suspect you’re mixing up iOS and macOS style app group IDs. Looking at that error, I see a group ID of group.M7288W…, where the group. prefix looks like an iOS style group ID and the M7288W… component looks like a macOS style Team ID prefix. If you’re building an iOS app, you must use the iOS style approach, and there’s no point adding your Team ID into the mix.
