Question troubles installing apps

[mannstill]

Windows 10 pro. Suddenly I can't install any more programs. "Installation failed", "installation blocked", "generic error" etc. even if I try to install as administrator. Has there been any important news in the latest system updates (which I have set in "automatic" and therefore I don't monitor)? I am sure that in the settings there is no limitation to accept only Microsoft Store apps
