Controller movement reversed / facing locked on one character only (new characters unaffected)

Description

I am experiencing a controller movement issue that occurs on one specific character only.

When using a controller, the character will:

Briefly turn to the opposite direction when starting to move, or

Move while facing the opposite direction

If movement input is held, the character may continue moving backward while facing the wrong way

This behavior does not occur on newly created characters.

What I have tested

Tried multiple controllers (same result)

Adjusted dead zones (no effect)

Disabled Steam Input (no effect)

Completely disabled right stick input (no effect)

Switched to keyboard & mouse and played for a while, then restarted (no effect)

Restarted the game and PC multiple times

Deleted local config files

The issue persists only on this one character.
New characters work normally with the same settings and hardware.

When it started

The issue started suddenly.
The same character worked normally until the previous day.

Expected behavior

When moving with a controller, the character should face and move in the same direction consistently.

Actual behavior

The character’s facing direction appears to be locked or desynced from movement input, resulting in reversed or backward movement.

Conclusion

This appears to be a character-specific input state issue saved server-side, rather than a hardware or configuration problem.

Additional notes

Keyboard & mouse movement works correctly

Controller movement works correctly on other characters

This feels like a character-specific input/facing state being corrupted and not reset on login
