Yesterday I updated my macOS to 15.?.2 and now my MacBook wont boot. I've made a Recovery on sdcard, on a ssd drive, Ive tried Command R, Option Command R, Shift option command R.
I did system update. I have two volumes? HD, and another. I booted "another" and did an update. The system sees HD and another but they don't boot. Recovery doesn't work. I have a time backup.

macOS 15.7.1 is the current version of Sequoia at this time.
What's new in the updates for macOS Sequoia - Apple Support
Updates normally require several automatic restarts and should not be interrupted during that process.
If an update failed and you can not startup in recover to repair or reinstall..?

Then it sounds like a hardware failure that is going to require service.
