Cant select version when making new installation
For a server i wanted to create a new installation with the version 1.15.2
Sadly, when I attempted making the installation, nothing happened. I could put in the name and select the icon, but when I clicked the version tab, nothing happened. I couldn't make a new version because of this. I tried fully reinstalling the launcher, and logging out and the in to my account, but with no luck. I could find I solution, but I didn't fully understand it.

Hi,
Please be aware that if you are creating an installation while in "Airplane mode" on Windows, and you have no internet connection, the launcher will fail to retrieve available versions and the list will be empty.
Assuming you have internet connection, when you click on the Installations tab, please make sure you tick one of the available version types, such as "Releases". This filter also affects the creation screen.
Did any of this help solve your problem?
