\pard\pardeftab720\sa240\partightenfactor0

\f1\b0\fs24 \cf0 Cubase 15 crashed (EXC_BAD_ACCESS / SIGSEGV) on the main thread. The fault is inside the 
\f0\b Kontakt 8
\f1\b0  VST3 plugin (Native Instruments), not in Cubase's own code \'97 a mouse-move event routed into Kontakt's Qt-based UI hit a null/invalid pointer.\

\cf0 NI_6_6_1_R5
\f1\fs24  is Native Instruments' internally-renamed copy of Qt 6.6.1, statically linked into Kontakt 8. The crash happened while AppKit delivered a routine mouse-moved event to a Kontakt 8 plugin window; Kontakt's Qt tablet-input handling code (
\f2\fs26 handleTabletEvent:
\f1\fs24  \uc0\u8594  
\f2\fs26 hasCapability
\f1\fs24 ) dereferenced a bad 
\f2\fs26 QInputDevice
\f1\fs24  pointer.\

\f0\b\fs36 \cf0 Interpretation\
\pard\pardeftab720\sa240\partightenfactor0

\f1\b0\fs24 \cf0 This is a 
\f0\b third-party plugin bug
\f1\b0 , not a Cubase core crash. It was triggered simply by moving the mouse over an open Kontakt 8 plugin window/UI \'97 the crash path goes through tablet/stylus input-device handling inside Kontakt's Qt layer, so it may be related to a connected graphics tablet (e.g. Wacom) or to how Kontakt queries input device capabilities on this system.\
Other NI components were loaded in the process at crash time: Kontakt 7 (7.10.9), NI's license-engine-access helper, and SINE Player \'97 none implicated in the crash itself, just present in the same process.\
