One of my team members is having trouble getting updates from collab. Every time he tries to download something he gets this error and the Editor closes. We have updated the project recently from unity 2017.4 to unity 2018.4 and collab to the last version (v2.0.0-preview.17) because the times of the "Checking for changes" were big (40+ minutes). Is there any solution, any files that are broken or old or any workarround to this problem? Thank you.
