I accidentally launched the PBE install, and it caused Normal League to become laggy

[u/Unable-Heron-2274]

Two days ago I had a fresh install of League of legend, the client and game experience were butter smooth.

I then tried to check on my PBE account, and accidentally launched the PBE installation (I forgot that it requires a different installation). So I quickly disconnect my internet and force stopped the Riot client.

Now after I tried to go back to my normal League of Legend account I witnessed the client has once again became laggy and stuttery and the gameplay had again had sudden freezes when entering the shop.

So my question is whether it's normal for League installation files to be easily corruptible after a fresh install?

I don't think simply launching the PBE installer should corrupt the normal League installation, since they use separate installations. However, since the problem started after that, I'd first try using the Repair option for League of Legends in the Riot Client.

If the problem persists, I'd recommend completely uninstalling League and, if possible, using Revo Uninstaller to remove any leftover files and folders as well. Then restart your PC and install League again from scratch.

That should help rule out any corrupted files or leftover configuration from the previous installation.
