I had upgraded the OS and now an application will not connect via the network today.

Windows 10 Professional
Version 1903
OS Build 18362.356 on both PC's

I have checked that network discovery is active on both PC's but when I start the application it asks me to browse to a folder on the other PC and when I try the error below appears:

Message=Cannot access a disposed object.
Object name: '#=qxixkFTjB97zwLvXjTU5Cghc4SWbPWdsXFnm4DFJJfG4='.

I have tried the .Net Repair Tool and that has not resolved the issue.

Any ideas?

Thank you.

Called Microsoft, tech person did a remote and installed "Windows.iso 1903.iso" on both computers but it did not resolve the issue.
