We currently suspect that the issue, especially the Windows Explorer hanging, is related to Windows Graphics Capture (WGC).
Based on our analysis, WGC capturing may lead to instability in certain environments, which could explain the behavior you are seeing. As a precautionary measure, we have temporarily disabled WGC.
Please retest the issue once the next version is available. In that build, WGC will be disabled by default. If you would like to continue using capture, please switch to DXGI and verify whether the problem still occurs.
We would appreciate your feedback after testing the updated version.
