Flone - React eCommerce Template By codecarnival - Theme not running

We have downloaded the Flone - React eCommerce Template

By codecarnival - The theme is not running on the latest platforms because of version specifications. The recent versions of the software and plugins the code is showing errors on while running. Please let us know who we can use the theme we have purchased. Thanks

Items from Elements are not supported by their authors.
You can purchase a copy from marketplace and request support:

We had a yearly subscription and downloaded the theme so why we again buy from the marketplace that will be the extra cost to us. Could you please let us know if there is any other way to resolve this. Thanks

As this is the reason you need to purchase the item directly from the author.
Otherwise, it’s something that you need to figure it out/solve by yourself.
