AMD has officially acknowledged a compatibility problem in its recently released Radeon Software: Adrenalin Edition 26.6.2 driver package, following a wave of user reports describing graphics card detection failures and startup problems on Windows 10 machines. The company confirmed the issue on June 23, 2026, via a dedicated support article on its website.

The driver was released on June 22, 2026, as a significant feature update. Among its headline additions were support for AMD FidelityFX Super Resolution 4.1 on Radeon RX 7000 series graphics cards, as well as game-specific optimizations for Assassin’s Creed: Black Flag Resynced and DOOM: The Dark Ages | Revelations. Despite these additions, problems surfaced almost immediately after release on Windows 10 systems.

What’s Happening

The issue primarily targets Windows 10 systems running version 21H2 or later. Following driver installation and system restart, affected machines fail to properly recognize installed Radeon graphics cards. Users encounter a yellow exclamation mark — commonly known as a “yellow bang” — in Device Manager under the Display Adapters section, accompanied by a Code 43 error, meaning Windows has halted the device because it reported a problem.

Beyond the Device Manager warning, AMD Software: Adrenalin Edition itself refuses to launch, displaying an error message stating that the version of AMD Software is not compatible with the installed AMD graphics card driver. For many users, this effectively disables all GPU management and hardware acceleration.

Windows 11 users appear to be entirely unaffected. No comparable reports have emerged from users running the newer operating system with the same 26.6.2 driver — a distinction suggesting the incompatibility is specific to the Windows 10 environment, possibly related to differences in kernel-mode driver handling between the two operating systems.

AMD’s Response

AMD confirmed the bug through an official support article, which carries a warning specific to this issue. The notice states that users running Windows 10 alongside Adrenalin Edition 26.6.2 may encounter a yellow bang in Device Manager affecting AMD Radeon RX series graphics, and that AMD’s engineering team is currently investigating the problem. A fix will be provided once it is available.

In the interim, AMD’s recommended course of action is straightforward: revert to the previous driver release, Adrenalin Edition 26.6.1, which was released earlier in June 2026 and does not exhibit this behavior. No specific timeline for a corrected driver or hotfix has been announced.

The timing of the bug is particularly unfortunate. The 26.6.2 release was one of the more anticipated Radeon driver updates in recent months, largely because it extended FSR 4.1 upscaling support to the RDNA 3-based RX 7000 series — a feature previously reserved for newer hardware. Windows 10 users hoping to take advantage of the improved upscaling technology will need to wait for AMD to resolve the compatibility issue before safely installing the update.

What You Should Do

If you are running Windows 10 and have already installed Adrenalin Edition 26.6.2, AMD recommends uninstalling the driver and reverting to the 26.6.1 release. For users who have not yet installed the update, holding off until a corrected version is released is advisable. AMD’s AMD Cleanup Utility can be used to ensure a clean driver state when downgrading. Windows 11 users are not affected and may continue using the 26.6.2 driver without issue.
