Hollow Knight Silksong Anti-Cheat Error on RX 7800 XT Fix

Quick Answer

An anti-cheat error in Hollow Knight Silksong on a RX 7800 XT is almost always a software handshake problem, not a faulty card. The fix is a clean reinstall of the anti-cheat service, an up-to-date GPU driver, and a verified game file pass — it rarely costs anything and takes about 15 minutes.

Why the error shows up on a RX 7800 XT

The card is not the cause. Anti-cheat services (EAC, BattlEye and similar) sit between Windows and the game, and they break when their installed service is corrupted, a security update half-applied, or the RX 7800 XT driver is mismatched. The 16GB GDDR6 on the RX 7800 XT has nothing to do with it; treat this purely as a service-and-driver repair.

The fix, in order

Work through these in sequence and stop when the error clears. First, fully close Hollow Knight Silksong and the launcher, then run the anti-cheat installer found in the game's install folder and choose Repair or Reinstall. Second, verify the game files through your launcher so any corrupted protection file is re-downloaded. Third, update the RX 7800 XT driver to the current release and do a clean install with the previous driver removed. Fourth, reboot — not just the game, the whole machine — so the freshly installed service registers properly. If it persists, temporarily pause third-party antivirus, which frequently quarantines the anti-cheat driver.

When it is actually a hardware or storage issue

In rare cases the error masks a failing drive or unstable overclock. If verifying files repeatedly finds new corrupt data, test the SSD's health — a failing NVMe drive is a common culprit and a fresh 1TB or 2TB SSD (stocked at Evetech) is a cheap fix. Reset any GPU overclock to stock; an unstable RX 7800 XT clock can corrupt the anti-cheat handshake even when games otherwise run. Keep the system on stable power so writes never interrupt.

FAQ

Will reinstalling the anti-cheat delete my Hollow Knight Silksong save?

No — the anti-cheat service is separate from your save data, which lives in your profile or cloud sync. Repairing or reinstalling the protection service and verifying files leaves your progress untouched.

Do I need a new RX 7800 XT or driver to fix this?

You do not need new hardware — the RX 7800 XT is not the cause. You do want the current driver, since a clean, up-to-date install resolves most anti-cheat handshake failures on its own.

Why does the error come back after an update to Hollow Knight Silksong?

Updates sometimes ship a new anti-cheat version that the old installed service rejects. Re-running the in-folder anti-cheat installer after each major patch keeps the handshake current and stops the error returning.
