Trisquel 12 ISO doesn't boot on my PC

Hi, I've been using Trisquel 11 ISO for certain tasks and liked it quite a lot. I prefer to not install systems but run them from RAM (Trisquel 11 stock ISO can be booted to RAM with "toram" parameter in GRUB), so I depend on ISO images and updating to Trisquel 12 every time from 11 is unfeasible. Trisquel 12 doesn't boot, unfortunately, the loading image freezes and nothing happens. I will probably not have the time to assist with fixing this, but I hope that this report would be useful. I'd characterize my PC as "modern" and "normal". I'd prefer to avoid sharing more details. Trisquel 11 takes some time to boot for some reason (5 minutes, not counting loading to RAM), but it boots on my PC. I've been trying to boot this ISO:

I wanted to post this on GitLab, but my registration hasn't been confirmed for more than two weeks...
