In remote desktop from Windows 10 to Windows Server,
When launching a business application running on RemoteApp, to some screens
When transitioning, the remote connection is suddenly disconnected without warning and disappears from the screen.

When you connect again, you will return to the screen just before the disconnection, and after that,
You will not be disconnected even if you operate on that screen.

This phenomenon occurs every time a remote connection is made.

I want to do something because it is very inconvenient to do business.
What should I do?

[Connection source PC]
Windows 10 Pro ver 1909 (latest 2020/02/07)

[Destination server]
Windows Server 2016 Standard (latest as of 2020/02/07)

[Trial]
・ Inquiries to business application developers
Result: The cause is unknown with a single point of "bad remote connection"

・ Change of group policy on PC side and server side (both were tried in the same way)
Remote connection related to local computer policy
・ Use advanced RemoteFX graphics for RemoteApp → Enable/Disable
・ Allow desktop composition of remote desktop session → Enable/Disable
・ Selection of RDP transport protocol → All patterns after activation, invalidation
・ Restrict Remote Desktop Services sessions to one for Remote Desktop Services users → Enable/Disable
I also tried what I looked up on the Internet.

・ Edit .rdp file
・ Uncheck printer and clipboard of local resource
・ All patterns of image quality setting change

If i have any solutions or good things to try, thank you.

    When launching a business application running on RemoteApp, to some screens
      When transitioning, the remote connection is suddenly disconnected without warning and disappears from the screen.

    I'm sorry that it is not an answer, but I would like to check from this perspective.
    First of all, it is said that the connection is suddenly disconnected, so we assume that a load has been applied around the network on the remote side, and monitor the network usage such as a network monitor.
    By the way, the meaning of running on RemoteApp is the intention of an application running on the remote side that is connected remotely, right?
    Since it was when the business application was started, does it change immediately before and after the start? I don't know if business apps use networks in the first place.

    Then, on both the remote side and the client side, is it necessary to replace the NIC or check if the problem occurs just by leaving it unattended during the remote connection?
