Your log contains quite some errors, some critical, some not:

- Multiple `Unknown command` (uncritical but still means you are feeding erroneous commands)
- `Move out of range: 235.140 174.063 97.050 [20600.913]` (which I believe killed your print) → [Move out of range: X Y Z [E]](https://klipper.discourse.group/t/move-out-of-range-x-y-z-e/6637)
- `Transition to shutdown state: Unable to read tmc uart 'stepper_x' register DRV_STATUS` → Only once, seems not an issue
- `Transition to shutdown state: Lost communication with MCU 'mcu'` → [Timeout with MCU / Lost communication with MCU](https://klipper.discourse.group/t/timeout-with-mcu-lost-communication-with-mcu/6639)

With a 16MB log and various errors it is kind of hard to say which one is spoiling your fun.
