Error Updating Addons

Hello! I am encountering an issue while trying to update two plugins: “Addons Manager and Support” and “Import/Export” for my WordPress site.

During the update process, I receive the following error message for both plugins:

“An error occurred while updating Newsletter – Import/Export: The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10): Invalid archive structure.”

“An error occurred while updating Newsletter – Addons Manager and Support: The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10): Invalid archive structure.”
Could you please assist me in resolving this issue?

Additionally, when I check the version details, I see the message “Plugin not found.” We have already tried deactivating and reinstalling the addon.

Versions:
Newsletter – Version 8.5.9 (latest)
Addons Manager and Support – Version 1.3.0
Import/Export – Version 1.5.1

Thank you for your help!
