Installation fails at creating partition

Issues & Assistance
1

I’m trying to install cachyOS on an external M.2 SSD on a Laptop that has two internal ssds, one of which has win10. This is the first distro I had problems installing so far( I used endeavour, garuda, nobara and Ubuntu before).Windows is able to create a partition on it, cachy is not.
I’m not very experienced and I don’t have very good Internet right now to download some other distro.
I tried partitioning with kde partition manager, also didn’t work.
Here is the log: https://termbin.com/rr6d

Any help is greatly appreciated

As far as I understand, the error may be happenning because the installer doesn’t know what file system to use. Perhaps, you could try manually choosing one. I’m kind of a noob, so take it with a grain of salt, but it wouldn’t hurt to try it out.

I tried that, it unfortunately fails as well. I also tried to manually partition with the official guide, that fails too.

Could you run sudo fdisk -l and see if everything looks OK in the output?

The only thing that stands out to me is the I/O size of the first SSD(which is the one I want to install cachyOS on), but I don’t think it matters.

Yeah, I’m sorry, I have no idea. You’ve probably already done that, but make sure you’re using the latest ISO.
