Yeah, the animation will play an nothing happens. That only occurs then you increase the max stamina in the gamplay.json, leaving it as the default value of 100 doesn't cause any problems for the server I run

It seems to be if you mess with new inertia settings it freaks it out

It's under the gameplay.json
And it's the max stamina and (keep max stamina at 100)
"MovementData":

		{
			"timeToStrafeJog": 0.1,
			"rotationSpeedJog": 0.3,
			"timeToSprint": 0.45,
			"timeToStrafeSprint": 0.3,
			"rotationSpeedSprint": 0.15

If the max stamina is messed with you cannot sprint and if the moment data is messed with it soft crashes. So just restoring these values to default seems to fix the problem. And for those wanting more stamina.
They can change
"sprintStaminaModifierErc":
"sprintStaminaModifierCro":
These effect sprinting and don't cause crashing I have mine at 0.02

I found out the problem. I has to deal with server settings involving the new inertia for sprinting. If those are changed and of the total stamina are changed the game crashes upon either sprinting or interaction

Ok it's just loading in the game now causes it to crash. Currently unplayable
