It's my first post but, seems i need to tell my problem:

Linux distribution and version:
Linux Mint 22.3 Zena (Cinnamon), 64-bit (based on Ubuntu 24.04 Noble)

Opera version:
Crashing version: 136.0.6008.80 (and presumably all newer versions)
Working version: 135.0.5973.76

Opera 136.0.6008.80 fails to launch entirely. Upon executing the opera command in the terminal, the browser crashes immediately with an Illegal instruction (core dumped) or Trace/breakpoint trap (core dumped) error.

Did this happen because of an AVX2 compatibility issue? Right now I'm using Opera GX, and the newest version works fine. If this happened because of a compatibility issue, I might consider using Opera GX, but I don't know if Opera GX will eventually require AVX2 as well.
