The trench is dug, now I just to bury all this!

I have designed a PCB which contains a USB-C connector an ESP32-H2. I've done this as a learning exercise more than anything, so I can a) solder an ESP32-H2 module and b) get a working USB connection for flashing.

Whilst the board powers up, I cannot get the device to appear under USB, so I cannot flash it.

D1 indicates 5V is coming from the USB. D2 indicates 3.3V from the LDO.

I've never soldered a non-castallated module, so I'm looking for any advice on how best to do it. I'm using an MHP50 mini hotplate to perform the soldering. I've partly convinced myself I need a hot air station for this sort of work, but I'm reluctant to spend the money!

I'm looking for any tips and tricks here.

Of course, there could be a flaw in my design, so I've also attached my schemtic and PCB.

Any help would be appreciated!
