I flashed MuOs onto my RG 35XX 2024, and does not boot with it in, if i switch out the sd for the default one, it boots fine (i accidentally booted up garlicOS on that one so it does not load at all, but it does boot)
The RG35XX 2024 is a downgraded version of the 35XXPLUS.
You need to have RG35XX + written in the back for it to be the 2024 edition. If it just have RG35XX, without the +, it is na original RG35XX, not supported by current releases of MustardOS.
Since you brought garlic up, I believe that’s your case.
