Java application startup suddenly extremely slow

Since yesterday I experience a very strange issue. I'm a dev so I already spent 12 hours solving this issue with no success prior to asking this question.

My configuration: Windows 10 Pro 64b, 1803. Latest Java 8.

Start up time of every Java application is 100x larger than the previous day. For example, "Configure Java", i.e. javacpl.exe takes 3 minutes to start, Pycharm takes 20 minutes start etc. Once started, everything works nominally. Once closed, the start up time issue repeats.

I have already reinstalled Java, even tried Java 11 to no improvement. I reinstalled all applications affected, no improvement.

During the startup, the application runs high on CPU (1 thread 100%), with no disk or network activity.

I do not think I changed anything in previous days that would affect Java. Only thing that stands out is Cumulative Windows Update 2018-11 that installed. I believe there must be other people experiencing this.

I would like to fix this without the need to reinstall Windows.
