I know this post was a year ago but I can’t find the special bundle of brushes for skin and pores. Is that something you can post again? Your help is much appreciated.
The one from Vector-Stock can be directly downloaded from here via right-click on the link and choosing “Save target under” (or similar meaning, depends on your browser) and you have to cut off this →
@Paulo, I’ve tested this with the brushes you show, but for me Krita does not crash using Windows 10 Pro and Krita 5.2.11 to which you should update first in the case you haven’t so far.
If you are up-to-date, you can try if rebuilding your resource database will solve this for you, but the chance is 50/50 that it solves your issue.
