I am unsure if some update to TeamViewer 9 in the last couple of days broke it (doubtful?). Otherwise, it appears that updating my Windows 10 computer to version 2004 has caused this.
I had a TeamViewer 7 Business license that was transferred to version 9 while v7 was being phased out. Everything was fine last week, but now I am unable to connect to any of my clients.
Here are some screenshots of errors/version numbers from my computer and one of my clients that I am unable to connect with.

Also, do I contact email support/open a ticket as a paid customer? There seems to be no way to that and the "submit a ticket" button goes directly to the public forum.
