BSOD on new Windows 11 Install - ATTEMPTED_SWITCH_FROM_DPC

JetSetter

Whenever I try to access the webcam using Teams/Zoom - I get the BSOD with the ATTEMPTED_SWITCH_FROM_DPC message.... If I uninstall Bitdefender Total Security - then the BSOD stops and after installing it - it comes back in a few days... Have the latest update from Dell as well as Windows Updates....

I have also had this issue. As a workaround, in bitdefender, go to privacy settings>Video and audio protection, and ensure that camera is enabled for Zoom. Whenever a blocked app tries to access the camera windows 11 seems to BSOD for me...

Yup, had the same issue with two different Dell XPS laptops. All I had to do was open the Windows 11 Settings and attempt to work with the camera, and got the BSoD. Took me a month to figure out the issue, and uninstalling Bitdefender fixed it. The workaround may possibly work, but I am still reluctant to install Bitdefender on that machine until a real fix is provided. I use multiple video call apps (Zoom, Google Duo, Microsoft Teams, etc.) and it seems ‘excessive’ to have to do all of those enablements - especially if I ‘accidentally’ use W11 settings to open the camera.
