Most Intel cpus from 2008 were core2-duos. I do not think it supports AVX and SSE4.
That change to use those happened after Qt 6.6.3, so you could try installing and running Sigil 2.2.0 and see if that has the same issue.
Qt6 is now testing a patch to remove the need for AVX and SSE4 support which they will hopefully integrat for Qt 6.8 final and Qt 6.7.3 when they are teleased.
