Hi @Delcio Horacio, This is a permissions related issue for external users. External users should have Read permissions on the app catalog site where you have deployed SPFx solution. You have to grant permissions to All Users(membership) on app catalog site where your SPFx solution is deployed. Follow below steps:

1.  Turn ON external sharing for your M365 tenant.
2.  Download & open SharePoint Online Management Shell and run below commands using administrator account:
3.  Connect-SPOService -Url https://<tenant>-admin.sharepoint.com
4.  Set-SPOTenant -ShowAllUsersClaim $true
5.  Grant "Read" permissions to All Users(membership) group on App Catalog (https://<tenant>-admin.sharepoint.com/sites/AppCatalogSite/_layouts/user.aspx) or on "Client Side Assets" library (https://<tenant>-admin.sharepoint.com/sites/AppCatalogSite/ClientSideAssets/AllItems.aspx) in App Catalog site as shown below:

Note: You need SharePoint tenant administrator and App catalog site collection administrator (SCA) permissions for running the commands. Reference: SPFx web part error for few users : Failed to load component
