Network Atlas crashes after updating to 2022.4

After upgrading my platform from 2020.6 to 2022.4 Network Atlas was uninstalled.

The issue is that I didn't know this would happen and with that several of my maps were affected. Custom icons are now just colored square icons.

I managed to install Network Atlas again, but I always get the error: (connection to the information service has been lost and could not be established again).

So I went to try to repair SWIS and I noticed that it is no longer in the Server Control Panel.

I tried to reinstall but I can't find the installer, it is no longer in the directory: (ProgramData/SolarWinds/Installers)

Can someone help me? All my NOC panels were done through Network Atlas.
