Well... I'm confused... Sometimes it worked, sometimes it didn't. After much trial and error, it seems to be working now, but I don't know why.
I have both the 22.130.0.2 driver from Dell, and the 22.150.0.6 from Intel installed. In device manager, Bluetooth, I can select the Intel(R) Wireless Bluetooth(R) device and change the driver. I had originally removed 22.150.0.6 from Control Panel, Add/Remove Programs. That allowed me to install the Dell driver. They both appear to work.
I did find one post on a Dell site that said to delete and re-add the pen from the Bluetooth devices. I've done that multiple times. What I've noticed is that my pen still works after deleting it. I can select text and move windows around. What doesn't work is the button on the end of the pen. That appears to require Bluetooth.
I also noticed that the icon for Pen & Windows Ink Settings is showing in the system tray icons. I don't think that it was always there. When you have the problem, does that show up? You can enable that in the taskbar settings. https://tencomputer.com/use-pen-windows-ink-on-windows-10/
I wish I had a good answer for everyone who has this problem. Sorry. If you don't use the pen much, it looks like you can just delete it from your Bluetooth devices. That way you can leave Bluetooth itself turned on.
