ah my bad, I misread, I thought you had tried sudo waydroid app install.
Failed to get service waydroidplatform usually happens when something fails when communciating to the container, this usually means the container is partially loaded so you will need to stop it and start again, you may even need to do a full reboot
You need a custom kernel, or a kernel module plus DKMS and kernel headers for your current kernel.
You also need the package that handles whatever filesystem they use for their containers.
Then, you need to be running it on Wayland or else it doesn't work.
The part that I'm stuck on is running games, which gives an error about not being able to find libmain.so, which might be an architecture mismatch problem. Maybe I can virtualize that part? But at that point I might as well just buy a phone.
can you report your issues to the waydroid github or check on the fedora forums? the matrix and telegram chats are always open to help too if you have a bit of patience.
