Can't open any of my songs after Windows 11 update

After Windows updated on Saturday Cantabile won’t open ANY of my songs. I get the following error every time I try to open any song either directly or through a setlist: “Failed to open song - an error occured during a re-route operation.” This was occurring on Build 3702, so I renewed my license and downloaded 4168. It loaded my songs and got me through a gig on Sunday.

It is now Wednesday, and build 4168 is now doing the exact same thing. Is anyone else experiencing this? Any ideas?
