Hi,
It doesn't tell in your case so checking, are your site pages classic- or modern sites?
If Modern, then save site as template is not supported as outlined https://learn.microsoft.com/en-us/sharepoint/dev/general-development/save-download-and-upload-a-sharepoint-site-as-a-template. You should then be using https://learn.microsoft.com/en-us/sharepoint/dev/declarative-customization/site-design-overview or possibly PnP Site Provisioning.
Ours are classic sites in Microsoft Project Online (MSPO/PWA) instances.
