To be able to publish extensions, you must have the SUPER Permission Set. Check to be sure you have that.

Make sure you have permissions assigned but not for a specific company:

Hello Sahib,
This error is specifically related to Extension Management permissions. Microsoft states that to install/uninstall Marketplace apps or upload PTEs from Extension Management, the user must have the EXTEND. MGT. - ADMIN permission set (or the D365 Extension MGT group); being a Microsoft 365/tenant administrator alone does not automatically grant this permission. If you already assigned EXTEND. MGT. - ADMIN, check the user card and make sure the Company field is blank on that permission-set assignment so it applies to all companies/environment-level operations, then sign out/in and retry. You can also open Effective Permissions for that user to confirm the permission is actually effective rather than only assigned indirectly. For a PTE, another option is to deploy it from Business Central Admin Center → Manage Apps; Microsoft states that an authorized Admin Center administrator can upload/install a PTE there without requiring additional permissions inside the target environment.
Regards,

Hi, the important part of the message is missing.
From what I can say there are two usual cases. The user who publishes from VS Code doesn't have the extension management permission set (D365 EXTENSION MGT, or EXTEN. MGT. - ADMIN in newer versions). SUPER covers it too, but check it isn't limited to one company only.
The other case, the publish itself is fine but your install or upgrade codeunit touches a table where the user has no rights, or the license doesn't allow it. Permission set can't give more than the license, so a Team Member or similar user will fail even with SUPER.
Glad to help - follow up if anything is unclear.
► If this solved it, marking it verified helps others too.
