In case we install many extensions in the same environment , they may conflict, if they have chunks with the same name (number).
This because the ModuleFederation plugin applies to chunks a scope based on the name in package.json.
To fix this you on your extension you can try to change the name in package.json or use uniqueName option.
We should solve on MapStoreExtension this using the extension name as uniqueName.
