Here is a new issue after upgrading to 26052, cannot unmute the sound, this is a GMKtec M2 PC, same machine works fine with Build 26040 and any other build.
Reproduced the same issue with a DELL XPS 8940 with Intel UHD Graphics 750 and Driver 31.0.101.5185 and the same with much older driver version 31.0.101.4302. With Dell XPS 8940 there is also a worse symptom using the latest Intel driver 31.0.101.5186 and cannot even complete the booting sequence.
