Created attachment 179653 [details] logs SUMMARY activating the colorize mask tool gives me an error pop up. i believe this might be connected to my brush resources. Ignoring this does not crash krita immediately but led to instabilities. i removed all my resource bundles and now it seems to be stable even after encountering these errors. Error from activating colorize mask: Krita has encountered an internal error: SAFE ASSERT (krita): "column >= 0 && column < d->colorMatrix.size()" in file C:/builds/graphics/krita/libs/pigment/resources/KisSwatchGroup.cpp, line 150 STEPS TO REPRODUCE I can't exactly say what caused this but the last thing i did before i started noticing these issues was installing the following 2 brush bundles: - Pesi's_Watercolors_for_K5_v_2.3.bundle - Rakurri_Brush_Set_V2.0.bundle OBSERVED RESULT SOFTWARE/OS VERSIONS Windows 11 24H2 26100.3476 Krita version: krita-x64-5.3.0-prealpha-9b27d338-setup.exe
