Hi I'm new here

Hi I'm tw_fan I'm new here. I actually came here to get help with my new R4 3DS Upgrade SDHC Revolution Gold Pro2019. I can't find the right software for my R4 card. Whenever I try to start it, it just shows an sd card with a question mark and menu underneath

I've tried multiple websites but none of them worked. I already tried asking in another forum but didn't get any helpful answers. This R4 card isn't my first but I couldn't find the newest software for my flashcard

Could you please...
