MCreator Existing workspace error

In most cases all Gradle errors are caused by one of these:

• Firewall or antivirus blocking MCreator
• Slow internet connection
• Your ISP blocking certain websites
• Too slow VPN or VPN with blocked domains that MCreator needs to access
• Any other software blocking access to download repository

The most common errors from Gradle are caused by firewalls or antivirus software. If you have any issues, we recommend you to temporarily turn off this software and try again. If this works, add MCreator as an exception to your firewall or antivirus or reconfigure the software properly to not block programs such as MCreator.

It can also happen that the servers from which Gradle downloads files (Minecraft servers, Minecraft Forge repo, Maven repository) are down and you might just need to try again later in such cases.

In some cases of unstable or slow connections, running the setup multiple times and when it fails with errors related to the internet connection (timeout errors, failed to connect, failed to GET, HEAD, ...) clicking re-run the setup multiple times resolves the issue as eventually, all files get properly downloaded.
