This seems to happen when the system has a dGPU and an iGPU in the same system and drivers are installed for both GPUs. The client correctly identified them but doesn't set-up the slots correctly. There are two issues here:

1. The AS/WS providing a CPU WU to a GPU Slot
2. The GPU Slot running a CPU WU.

Issue 2 Potential Solution
Ensure that the GPU Slot can't run FahCore_a4 and FahCore_a7.
Ensure that the CPU Slot can't run FahCore_21 and FahCore22.
If we start with a blacklist, new versions of the FahCore will not require a new release of the client and the names can change without any issues. The next version can update the blacklist. Since new FahCores are not frequently released, it seems like a good sanity check IMO.

It seems that if a new dGPU was added manually to the GPUs.txt file on the local system, it produces the similar result, a FahCore_a7 WU running on the GPU Slot: https://foldingforum.org/viewtopic.php?f=83&t=35325

Manual changes to the local GPUs.txt are prohibited -- but folks still try to hack FAH. Whatever the local cached copy says is checked by the server and that master copy should always take precedence. Inasmuch as no Intel GPUs are currently supported, it becomes a question of what the server is supposed to do when a device (that from FAH's perspective) doesn't exist requests a new WU assignment.

1. IF DEVICE=[a supported GPU] THEN Assign a GPU WU. Condition = false so the server handled this correctly.
2. ELSE IF DEVICE=[CPU:n] THEN Assign a CPU WU. This condition should never happen here. Since it is ambiguous it was incorrectly handled.
3. OTHERWISE issue a message message "No WUs can be assigned to your hardware configuration."

The third condition needs to be added to the code.
