Hello, curious if anyone here is experiencing this with their windows device in the egpu community. 

Updated my Dell XPS 15 9500 to the latest windows 10 version and now I cannot connect any Bluetooth devices, and when I turn my Bluetooth off - my computer freezes for a second and restarts. No error message or anything happens - it just restarts as if nothing happened. My computer will boot up and my Bluetooth will always automatically be on and connected to a Bluetooth speaker I own. The other problem is the Bluetooth speaker (previously mentioned), shows up and says connected, but it is nowhere to be found when I go to sound settings->sound Input/output, so I can't even use the speaker despite it being connected via Bluetooth. I also cannot add any new Bluetooth devices - my wireless headphones do not show up at all when trying to pair. The current speaker that is default connecting has up to date Bluetooth drivers. I have no idea what the problem is, but I also haven't done much as far as installing/reinstalling things. 

I have scoured the internet for answers and it appears this recent update has caused Bluetooth problems, but I haven't found anyone talking about a case where turning Bluetooth off or on results in the computer shutting down. Side note - all of my devices hooked up to my razer core x chroma work just fine, including a Bluetooth wireless mouse. This has been extremely frustrating and would love to hear any input or if anyone else has had these problems. 

Thank you.

I have never heard of Bluetooth causing a system restart, what a horrible issue. 

The first thing I would try (if you have not already) is reinstalling your Wi-Fi + Bluetooth drivers and manually remove all previous Bluetooth devices. BEFORE doing this, Download the latest Bluetooth and Wireless drivers directly from Dell.

Once you have them downloaded, navigate to Device Manager. Click "view" and select "show hidden devices". Now open the Bluetooth tab and remove all the 'hidden' devices you recognise by right clicking on them and selecting uninstall. If given the option to remove software when uninstalling, do it.

Once you have completed that, under the Bluetooth tab, right click on the primary Bluetooth device (Usually called Intel Wireless Bluetooth) and select uninstall. Make sure you also select to uninstall driver software. Do the same for your Wi-Fi drivers, which will be under the Network Adaptors tab. A better guide can be found here.

Install your already downloaded Wi-Fi + Bluetooth drivers and see how it goes.

Update - It appears there are many issues with the newest Windows 10 update (2021-04 cumulative update for windows 10 Version 20H2 - (KB5001330)) causing a myriad of problems, as mentioned in this Techradar article ( https://www.techradar.com/nz/news/new-windows-10-update-is-causing-a-whole-world-of-pain).

I did not end up uninstalling and reinstalling my wireless and Bluetooth drivers in fear of causing a larger headache, but this could help still, but I will continue to wait as this problem may be due to a windows update. I may just uninstall the above mentioned windows 10 update and see if everything works fine on the previous update. I had to download Intel Driver and Support Assistant (a separate program from Intel's Support Assist where I had gotten all previous updates - I know, incredibly stupid there are two separate apps for updates) to download the newest Bluetooth drivers (Intel Wireless Bluetooth version 22.4), but when doing this my computer crashes every single time and blue screens with the errors: System thread exception not handled, system service exception, and attempted execute of noexecute memory. Errors seem to cycle and result from the same issue all revolving around bluethooth - turning bluetooth off (crash), updating bluetooth (crash), troubleshoot bluethooth (crash).

 

TL;DR Microsoft needs to get their shit together and release an update that doesn't cause several more problems while fixing less.
