Soldier 76 jump bug

I have tried reinstalling the game but the issue persists.
When I have “Hold to sprint” active and I sprint the jump doesn’t work.
I can jump fine if sprint is set to toggle, any ideas on what is going on?

Try a different keyboard model.
It’s possible they keyboard cannot process this particular key combination. This is a bit of a far cry but you should test it anyway before you try other things.
