@burnout426 Yes, that's the version.
A standalone installation doesn't crash. So what can I do next?
The only extensions I have on my browser are Opera Ad Blocker, which is on. Opera Wallet, which is off. The Honey coupon extension, which I've had for years without these problems and has been off since it crashed the first time. And Session Buddy, which I've gotten after the crashing started in hope it will keep my tabs safe, it has also been off since one of the last crashes. It has crashed even with them all off, so I wouldn't expect them to be the culprits.
