VS19 + VS22 causes error - Visual Studio 2017 support for ARM64 is not installed - visual-studio

Question

I have a local building agent for a Unity|HoloLens-Project. The whole time I had VS2019 on the agend installed and everything worked well. Today I had to install VS2022 on my agent because of a different .net 6 project (so it has nothing todo with my unity stuff!).
However, after installing VS2022, my Unity project can no longer be built with VS2019. I get the following output:
EXEC(0,0): Error : System.NotSupportedException: Visual Studio 2017 support for ARM64 is not installed.

The whole thing makes no sense to me. If I have only VS19 installed everything runs. When I install VS22, I get this error message. I went back to the building agent myself and manually opened the project in VS19 and tried to creat/publish an APPX. There I got the already known errors displayed and one more:
System.NotSupportedException: Visual Studio 2017 support for ARM64 is not installed.

MSB8020 The build tools for v143 (platform toolset = "v143") were not found. To build using the v143 build tools, install the v143 build tools. Alternatively, upgrade to the latest Visual Studio tools by selecting the Project menu or right-clicking the solution and selecting Reassign Solution.
Workload in my VSInstaller for VS19:
It doesn't make sense that VS17 with ARM64 is suddenly demanded. And it makes no sense that suddenly the build tools for version 143 are required. The project is opened with VS19(=v142) and not with VS22(=v143).
