Hello,
I received my STM32F446ret6-based PCB for my student project, PCB was already assembled from the JLCPCB factory and I can't program it through the SWD header with ST-link. I checked every trace on PCB with schematic and measured continuity with a multimeter, but no luck so far, still no connection. So I'm here to ask if you could spare some time and check my schematic or PCB, where that mistake is because I have lost any hope that I can find it myself.
here is a link to Kicad 6 project on Google drive: drive
thank you

Nothing's jumping out.
Is orientation of part correct ?
Authenticity of part ?
Can you measure voltages at VDD, VDDA, VCAP, NRST (3.3, 3.3, 1.25, 3.3 ?)
Error from STM32 Cube Programmer ?
Wiring of ST-LINK to header ?
