Hello, I cleaned up the file plugin.json as you suggested, and I managed to install the plugin.
Now all nopcommerce breaks with this error: Object not found "FNS_TrackingCode".
In the database, I do not see any table "FNS_TrackingCode". I also checked the .sql files in the installation folder, and both "SqlServer.TrackingCodeManager.sql" and "UnSqlServer.TrackingCodeManager.sql" are empty. Is that normal?
