Did you test the latest prusa-aio-bugfix-2.1.x code?
Yes, and the problem still exists.

- A ZIP file containing your
Prusa_AIO_Configuration.h.
Additional information & file uploads
I’ll follow up with the ZIP shortly.
Your config builds & works fine here on an SKR 3 with TMC2209s, so I'm certain there is something wrong with your drivers.
Here's a copy of the firmware I built using your config: firmware.bin.zip
For good measure, here's my reply from your Facebook post:
For TMCs to work properly, they need full 12/24V power. Powering them via the motherboard over USB will result in a TMC CONNECTION ERROR. For TMC2209s on an SKR 3, you need to ensure jumpers under the drivers are set to UART mode. DIAG jumpers should only be installed under the X & Y drivers since those are the only axis used for sensorless homing (installing them on other axis will cause homing issues).
I also have some notes about your config, though none of these would cause the issues you're seeing:

The LCD displayed the printer name, no error, and sending M122 on pronterface read all OK. Out of curiosity, I swapped back to my second SD with the most recent firmware I compiled yesterday that was giving me the TMC connection error and it also worked fine today. I have no idea why and I hope it doesn’t come back because I don’t know what fixed it.
Glad you got it working!
