After few days of trying, even with a fresh install and a new ssd and all the suggestions I finally got it working.
The solution? Just smash it. Every time it would crash, I just kept starting it again and again. Sometimes might have tried to start it twice (all from the powershell, so it is fast to do). Each time it said it failed, I pressed cancel and did it again. Might even have force quit a few times before before it gave the option to cancel (by just closing power shell). Then it just suddenly moved on from the point it usually gets stuck, started normally and now seems to work started normally from the shortcut. The number of tries wasn't anything absurd either, might have been around 5-15.
On the other hand, it should just work.
Edit: After several reboots, installing other software, adding windows features etc. decided to see if it still works. Not surprising at all, it crashed on startup again. And as before, just starting it several times made it work. I do have the "--disable-gpu-sandbox" in my shortcut, but anyway. Didn't need to use powershell, just kept launching it, I think it took 7 tries this time. Now I can quit and start it normally again. Coincidence or not, I have 7 samsung SSD:s installed: 4 NVME drives and 3 traditional SSD:s. I have never seen a program this badly made.
Edit2: So I've been testing a bit more. For me, it doesn't seem matter if the --disable-gpu-sandbox is there or not. I just keep hitting "OK" for it to reinitialize. Longest time it took was a bit over 12 minutes, shortest was 1 minute 31 seconds. No logic there either. The only difference is that after that 12+ minute one is that I changed the "Auto refresh option" to 1 minute, which refreshes the drives status and performance. But don't know why that would matter.
