Base System Device driver missing for JHL7540 Thunderbolt 3 NHI [Titan Ridge 2C 2018] [Razer Blade Pro 17 - 2019 model, RZ09-0287x]

I have had to re-install windows (11)  on my Razer Blade Pro 17 (2019 model, RZ09-0287x) due to a failed/botched Windows Insider update.

Everything is now more-or-less working, but I am still missing drivers for a ‘Base System Device’, which is:

    Intel Corporation - JHL7540 Thunderbolt 3 NHI [Titan Ridge 2C 2018]
    PCI\VEN_8086&DEV_15E8&SUBSYS_30001A58&REV_06

I have installed all the drivers from the Razer support download page for my razer model, including the Intel chipset drivers, but the driver for this device is still missing. Similar reports for this missing driver for other Razer laptop models seem to indicate that this driver should be available from Razer (and in the intel chipset drivers), but this does not seem to be the case for my Razer laptop. I have also searched the internet and cannot find a driver for this device (just one for a similar card but for a HP laptop).

Does anyone know why this driver is not included in the Razer driver downloads, and where I can find/acquire the driver for this device?

Thanks in advance for any assistance,

John

I finally managed to find the drivers on the backup I managed to do of the old C drive before I re-installed windows. I found the drivers in the following location: \Windows\System32\DriverStore\FileRepository\tbthostcontroller.inf_amd64_7eff2fc15624ea0d

Driver files are:

    TbtBusDrv.sys
    TbtFilterDrv.dll
    TbtHostController.cat
    tbthostcontroller.inf
