I have a similar configuration. Everything works fine. Previously, there were errors on the Z axis, too, with two motors, but with TMC2130 drivers. Sometimes there was a message about a voltage drop, sometimes about the breakage of the motor windings, sometimes about the short-circuit of the windings. Sometimes on one, and sometimes on the second motor. Fixed by setting the option stealthchop_threshold = 0 (disable).

Same problem here, tmc5160 v1.2 and skr1.4t board. 2209s work fine. Have tried the 5160s in 3 different printers and yeild the same results. Gstat undervoltage error. The axis that throws the error is random. The drivers work fine on marlin. Have had the drivers for years now and have never been able to get them working with klipper. Super frustrating as I have around 20 of them sitting there. Did you manage to get any further with them?
