continued render farm issues

I've tried putting my scenes back up on the render farm as I assumed it would be fixed by now but I'm still running into errors, I think there might be an issue with my file, however I am confused as I had managed to render out those first 2 shots with no issues, and all of the issues started when maya updated to the 2020 version overnight. 

I had queued up all of my shots but after seeing 3 of them fail I thought there wouldn't be much point taking up the render farm if the files were going to fail. Chris was in the class and had a look,he thought the issue might have been because the computers were being used by another student rendering something, however there didn't seem to be any overlap, and the render farm had managed to render out 4% of one scene. but the rest had failed. pc-dt239-1712 managed to render out the set of 4 frames but later failed to render another set. a few other students had failed render issues to but some files were fine. at this point I'm really not sure where the issue lies.
