Webview 2 error fix/Invalid operation on log in

If you're getting an “Invalid Operation” message when trying to log into FFXIV, the issue is likely with a corrupted or outdated WebView2 Runtime. Here’s a step-by-step guide that worked for me and should fully resolve the issue:

1.) Download WebView2 Runtime: https://developer.microsoft.com/en-u...-edge/webview2
-> Download the Evergreen Standalone Installer (not the bootstrapper).
-> Don't run it yet.

3.) Boot into Safe Mode:

-> Press Win + R, type msconfig, and press Enter.

-> Go to the Boot tab, check Safe boot (Minimal), then restart your PC.

4.) Delete Corrupted Files:

->Navigate to: C:\Program Files (x86)\Microsoft

-> Delete the entire EdgeWebView folder.

5.) Install WebView2:

->While still in Safe Mode, run the installer you downloaded in Step 1.

6.) Exit Safe Mode

-> Open msconfig again.

-> Under the Boot tab, uncheck Safe boot and restart normally.

7.) Fix Any Missing DLL Errors

-> If you get a system error about a missing .dll file (like msedge_elf.dll), go to: Settings > Apps > Installed Apps
-> Find Microsoft Edge, click the three-dot menu, then choose Modify > Repair.

After doing this, FFXIV should launch and log in without any issues.
