Hello,
We can see next activations – https://prnt.sc/zqjbrb
According to the ThemeForest license policy, you can use 1 license for 1 project only (dev site, production site, localhost but the same project) – https://themeforest.net/licenses/terms/regular
Deactivate https://prnt.sc/zqjito and delete the theme from old sites, then you will be able to activate it on a new site.
Let us know if you need any further assistance
Regards
