[UE 5.7.4] Editor crashes when displaying the Control Rig list in Sequencer(Solve)

General Issues and Bug Reporting (Unreal Engine)
1

Summary

As an additional troubleshooting step, I increased the Windows TDR (Timeout Detection and Recovery) delay through the registry. However, the issue still reproduces consistently. The same behavior occurs with both DirectX 11 and DirectX 12.

What Type of Bug are you experiencing?

Steps to Reproduce

  1. Open a level.
  2. Open Sequencer.
  3. Add a Skeletal Mesh Actor to the Sequencer.
  4. Click + Track and select Control Rig.
  5. When the Control Rig list is displayed (or when searching for a Control Rig), the editor freezes for a few seconds and then crashes.

Expected Result

The Control Rig list should be displayed normally, allowing the user to select a Control Rig without the editor freezing or crashing.

Observed Result

freezing or crashing.

Root Cause (Observed)

The issue appears to be related to Windows display scaling rather than Control Rig itself.

Reproduction conditions:

  • 4K display
  • Windows display scaling set to 200%
  • Opening the Control Rig list in Sequencer causes the editor to Windows freeze and engine crash.

Workaround:

  • Reducing Windows display scaling from 200% to 150% prevents the crash.

This looks like a GPU driver device removal issue rather than the Sequencer itself. I’d test in a clean project, update or roll back to a stable GPU driver, and disable any overlays or overclocks. If it still reproduces, it’s likely a UE 5.7 regression worth reporting with the crash dump and GPU/driver details.
