Just wondering, how are you setting min and max heap now? By setting
Xms and Xmx values in the Java tab OR by setting values in the
"initial/max memory pool"? If you are using Xms and Xmx values, can
you remove it and try to set heap via "initial/max memory pool"
option? Just wanted to see if that makes any difference or not.

This is indeed interesting. I don't have any Windows 2019 but I'll try with
