Can you provide the APK file you tried to install so I can test on my end?

[EmilyTempest]

Here's a link to the .apks:
https://github.com/NuvioMedia/NuvioTV/releases/tag/0.7.8-beta

specifically tested the Universal and x86_64 versions, with the same result - weirdly enough, if I try to close the WSA Sideloader, it will also give me the same error as above

I also attempted this on some other random .apks I had laying around, same result
