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

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".

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.

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