Alain Melsens reports cache corruption on IIS with APCu caching activated. Specifically, he reports loss of plugin activation. That usually happens if the options|alloptions cache entry gets lost or damaged.

A conflict with a couple of session parameters (session.lifetime & session.gc_maxlifetime) in the php.ini file. I don’t remember exactly why I added these. Perhaps I read it somewhere on the Internet.
I removed them and now everything works correctly.
Now I can use APCu without any impact on the WordPress dashboard. I no longer get automatically logged out and everything now works correctly and also faster.
This task is to detect the situation and warn the user. (Or, if possible work around it.)
