I deleted every mod, and it still says Error: Could not find or load main class forge Caused by: java.lang.ClassNotFoundE what do I do

Reproduction Steps

• 1. I got some mods for forge 1.21.1 and then i wanted to start the server.
• still 1. then i tried to check the mods folder and there was a 1.20.1 folder so i delted it
• still 1. then i tried to start the server again, didnt work so i checked the console and it said Error: Could not find or load main class forge Caused by: java.lang.ClassNotFoundException: forge

Trimmed errors mean nothing, so there’s not much advice I can give in that regard.
You could delete the libraries folder, select the version of Forge you want, then press Download/Update to install Forge again.
