Hi,
Firstly, worth mention that the sample you've posted is related to "tracks". Of course, SKD point of view, that makes no difference. Secondly, it opens fine on my machine.. Are you sure you did not "blocked" some shaders from the editor ? Because the error seems to be there.. a shader that is not found.
Could you please check:
1/do you have these shaders under \STEAM\steamapps\common\assettocorsa\sdk\editor\system\shaders
Code:
ksFXAA_0
ksFXAA_1
ksFXAA_2
ksFXAA_3
ksFXAA_4
ksFXAA_5

1/ Yes, they all exist.
2/does your SDK editor work for anything else ?
2/ No. Always the same error.
3/did you "initialize" the editor after 1st time use ? (meaning not to see everything in B&W and low res)
