Hi, found this issue and managed to work around it so hopefully can help some others:

Repro Steps: 1) Windows 11 2) Run CMD as Admin 3) Change Directory to bt_driver folder 4) bias_tee_on

Result: image

Workaround: You can update your RTL_SDR V3 to always have the bias tee enabled.

I did this on a raspberry pi, but might work via Windows. 1) Instructions: https://github.com/rtlsdrblog/rtl-sdr-blog 2) Following doing this, moved the SDR v3 back into my Windows 11 PC. 3) SDR# could not find the device, so I used Zadiq to replace the drivers again. Then it worked.
