does anyone know how to fix this?

[E2754]

So every time I try to install wumiibo from the app it always gives me an error saying "verification failed. please manually install the app. Press b to exit." and I've been trying for a while to get it working and searched through many threads with none solving my actual problem. So if anyone knows what to do, please help me. I just want Tangy in my village 😢

Try deleting all Wumiibo files on the SD card, uninstalling through FBI and then install wumiibohelper with Universal Updater. Then press install again

That does not fix it
