Hello, should the LEDs light up after connecting the adapter to the computer?

I was also seeing the message saying I needed to turn my vehicle on.

FWIW, I tried all of the suggestions from this thread that seemed relevant but my Windows 11 laptop with USB-C ports is not working.

The main diagnostic that helped me was to plug the USB-C directly into my phone and run the OBDlink app on the phone. This told me that the connection/cables were good and that everything SHOULD be working. After several hours of trying various things to reset the windows 11 laptop (including trying to download new FTDI CDM drivers, latest FORScan downloads, Updating the OBDLink firmware and even trying a previous verison of the firmware, Windows updates, etc) I tried my older laptop (also windows 11 but with USB-A ports) and it worked fine.

On the new laptop, I've tried several different usbc > usba adapters but always it can't connect. Plugging into different USB-C ports didn't change the com port. I've confirmed that neither OBDwiz or forscan work on that laptop (both are fine on the older laptop).

So, somehow, I've got the USB/Serial/Port/COM system mucked up and I haven't found a way to reset it all.

For completeness, I was able to go back to a prior firmware on the OBDLink EX using the USB-C laptop - so some portion of the communications software is working. But I could not get it to connect/sync with my vehicle. Furthermore, I was using that laptop earlier this year successfully. I sent my debug log to FORScan support and they said

Very weird, there is no active CAN bus on the adapter. Either something is wrong with the connection/OBDII port of the car, or your adapter suddenly died

not drivers but a firmware update (first one for 18 months) - with an interesting fix see bold

https://www.scantool.net/downloads/updates/obdlink_ex/

this release fixed a few bugs:

Fixed an issue where CAN multi-frame message transmission would cause the device to lock up after 35 minutes of uptime
Fixed handling of ATCRA, ATCF, and ATCM so their values are preserved when ATSP or ATTP are issued, matching ELM327 behavior
Fixed rare issue where an overflow condition could reduce message delay times
Fixed rare ISO 15765 flow-control frame transmission failure during concurrent multi-frame reception
Fixed INTERNAL ERROR when receiving more multi-frame messages than specified
Fixed ATCRA not restoring default filters when used without a parameter
Fixed bug, STPX now properly sends 29-bit CAN messages when the AT/ST protocol is configured to 11-bit CAN

This release also added a few new features and a change:

Added the Batched Commands feature, which supports sending multiple commands/requests in a single prompt
Added the STBC command for enabling and disabling the Batched Commands feature
Added the STBCOF command, which sets the output format for batched commands
Added an optional parameter to STM and STMA commands to exit monitoring after reaching the specified message count
Added the STITW command to set ISO protocol W timings
STCSTM now also sets ISO 11898 inter-frame delay for segmented messages
