Unable to open repo (large number of repos)

I have over 70 repos in my local machine. When SourceTree first opens it shows the list of repos and a "loading" icon next to it. After a couple minutes all the loading icons clear. However when clicking on the repos name they won't open.

I noticed however that clicking on the repos at the top of the list would open, while the ones at the bottom of the list won't. Also noticed that slowly more and more repos would open.

After about 12 minutes all repos can open now.

This was never a problem in previous versions of SourceTree.

My current version is 2.0.19.1 (the drop down on this form only shows the options "I don't know" and "Trying to upgrade"
