MacBook Pro 2019/Recovery Mode doesn’t show up any disk to install MacOs Software.

What happened is that I decided to set my Mac up as new, had some problems with my storage because of the 128GB model, so I did that and when I tried to erase the disk, it supposedly went through, I got the green check mark like meaning “successfully erased” then I noticed there was like 40GB of storage left, so it clearly didn’t delete everything at all, so I tried to do it again until the disk was completely erased, then I proceed to install the Catalina OS, and it just doesn’t show any Disk to install the software, even if I go to the corner where it says “StartUp Disk” nothing shows up, looks like it doesn’t recognize any Disk available, and I’m able to be at the recovery mode screen so that’s a good thing, because there’s no damage, and I never ever had any issues, I just bought it 3 months ago, it was everything literally perfect. Hope you can help me.

By the way, “Container Disk2” on the image doesn’t mount, I already tried that and it just doesn’t work.

And when I restarted it I got a spinning globe, and put my WiFi, after that it lasted around 13 min. Then I got the recovery mode again BUT, know it’s not Catalina what it’s trying to install, now it’s got Mojave.
