If the Lunar Client launcher opens and infinitely refreshes, it's likely due to having package.json file in your user folder.


Instructions


Step 1: Check your user folder

Windows:

  1. Press the Windows key and R at the same time.
  2. Copy and paste in "C:\Users\%username%\" without the quotes, then click "OK".


macOS:

  1. Open Finder.
  2. From the top menu bar, click Go > Home.


Step 2: Remove package.json

  1. In the folder that opens, look for a file named package.json.
  2. If you see one, right-click it and select Delete.


Step 3: Restart Lunar Client

Launch Lunar Client again. The launcher should now open up normally.
