No sound Windows 11

I'm out of sound in my Insider version of Windows 11, after restarting my computer it hasn't detected any audio devices.

I was running Windows 11 Insider Preview (co_release) without any problems. However, after I installed the 2021-07 .NET Framework 3.5 and 4.8 updates for Windows 11 (KB5004342) the sound card stopped being recognized. My laptop is Acer Aspire A515-54, model N8Q13 (it uses one Realtek SoundCard). As a test, I plugged a generic USB Sound Card and it worked fine. My steps to get it fixed: I unplugged the external sound card and went to System Settings > Sound > Troubleshoot  Common Sound Problems > Output devices > waiting for the fix > Restart. After the reboot, the driver was fully working.
