Content Library issues with vCenter 6.5 U1

I've tried to upgrade my homelab to U1 a couple of times over the last few nights and keep running into an issue with the content library service and having to role back.

After the upgrade which seems to go fine my content libraries dissapear and there is a warning on the vAPI service that it can't connect to an endpoint which I believe is the content library service (that is stopped), which is complaining on start attempt about a few missing setting files but nothing concrete to point me in any direction. Content library service will crash on start every time.

Just seen this and not sure if it's related: [Potential major(i'sh) bug in VCSA 6.5U1 - can you check](https://www.reddit.com/r/vmware/comments/6qvpfw/potential_majorish_bug_in_vcsa_65u1_can_you_check/)

I'll give that KB a look tomorrow when I get a change to try to upgrade again but has anyone else experienced this? Only other thought i'd have is to remove my content libraries before upgrade and see if something about them doesn't migrate well, but I've never had to do this before.
