Shield Guard Client Not Responding after Mainbuild Switch?
It sounds like you messed up your game files pretty bad. Deleting the install folder and hoping the launcher replaces it correctly is a classic way to break the Shield Guard client verification.
If the client is kicking you for "not responding" every few rounds, your file integrity is definitely cooked. The game is likely trying to load assets that don't match the checksums on the server side, leading to that desync/kick loop.
You're probably stuck on that build because the manifest file in your registry is mismatched with the files you dumped back in. Try a clean wipe of the Ubisoft folder in your AppData too, sometimes that cached trash keeps the issue alive.

- Clean Install: Don't just paste the folder back. Use the launcher to "Verify Game Files" or just bite the bullet and do a full reinstall to ensure no leftover config junk is hanging around.
- Shield Guard: It's aggressive as hell. If you're messing with the mainbuild, it's gonna flag any modified or missing files immediately.
- Testing: If you're trying to test internal stuff, make sure your offsets are actually aligned with the current version, otherwise you're just begging for a ban.
