I was also unable to open the back-up folder on the Time Capsule, I could connect to the Time Capsule, saw the back-up folder for my iMac, but opening it was impossible.

If I told it to make a back-up it would start the process, say 'preparing' and hang there. Time Machine hasn't been making back-ups since High Sierra was installed! It couldn't.

I'm currently working on the back-up restore part, but when I wanted to start on that I came across another issue. If that doesn't work the last option the guys saw was to just do a clean install and take all my files out of the back-up and put them back manually. The next step I am currently working on is putting back a Time Machine back-up through recovery boot, to see if that fixes things. So I grabbed a USB hard drive, and installed MacOS on that, which works flawlessly. We are pretty sure the MacOS installation is messed up in some way, which is weird since I already reinstalled it through a recovery boot, if a bit fell over during download or installation, a reinstall should have fixed it, but it didn't. I ended up setting up some steps with the second line guy, I would go through and report back with the results. They hadn't encountered this issue before, had some great ideas on the cause and possible solutions, but we were unable to fix it. I spent over an hour on the phone with Apple Care yesterday, the two guys who tried to help me were stumped.
