Remove All Client Modifications
If you have any of the following installed, remove them immediately:
- R-shade / ReShade — Makes graphics look "shiny" but is considered an exploit
- Exploit tools — Synapse, KRNL, Fluxus, etc.
- Cheat Engine — Even if it's not targeting Roblox
- DLL injectors — Any tool that modifies game memory
Roblox's anti-cheat (Byfron/Hyperion) scans your running processes. Even having these tools open — without using them on Roblox — can trigger Error 268.
