Knapster is the culprit--you seem to be using an outdated version. 1.22 introduced changes in the code that broke a lot of older mods. Luckily, Knapster is updated for 1.22, so updating the mod to the correct version should fix the problem.

i removed knapster but still have the issue

I ran into a similar issue when I added it whilst playing one of the early 1.22 RCs. I had to delete the folder for it in either AppData\Roaming\VintagestoryData\ModData or AppData\Roaming\VintagestoryData\ModConfig to stop the crash in additional to removing it from AppData\Roaming\VintagestoryData\Mods.

 

You should be able to update it to version 4.0.0 too as LadyWYT noted. That should update any additional configuration files that are causing the crash.
