Sudden random crashes since patch went live on 18.12.24

Have had a good run of almost hassle free daily gaming since the start of Dragonflight

Today though, within five mins of playing ive been plagued by random crashes to desktop.

The error message is always the same:

Program:D:\World of Warcraft_retail_\Wow.exe
Exception: 0xC000001D (ILLEGAL INSTRUCTION) at
00007ff719edaad3

Please dont tell me its the fault of my PC or the game installation - its been faultless for months, right up until this patch

Have tried with all addons disabled…no difference

Would genuinely appreciate a solution - Wow has suddenly become almost unplayable

same here but happen only one time I thought i accidentally ended game but not. Game ended self withou any error message
