I can try to put the rest of the crash report with "A detailed walkthrough of the error, its code path and all known details is as follows:"

I had this issue a few days ago when playing(trying updates) with my test server. At least I think its the same issue. Full crash reports are more helpful.

I solved this by reinstalling all the mods on the server. I reinstalled the backup of the server then went through one by one all the updates and it worked.

Hope it helps.
