Anyone can Help with NCA Magic Decryption errors when installing .NSP/.XCI?

I've been trying to install Life is Strange: Double Exposure for a while now and still seems to give me the same errors. My modded switch is on 19.0.1. Hekate, Atmosphere all the most recent. I have Sys-Patch installed from here the most up to date one. I try to use Tinfoil/Nut, DBI, Tinwoo/NXUsbloader... doesn't matter. They all give me the same error: NCA Magic Decryption Error. Failure to install.

I've tried to download the file multiple times from multiple different websites just to make sure and I'm sure they are all good downloaded files. It even works on the Sudachi emulator just fine. I just wanted to install it on my Switch.

Some other .NSP/.XCI install fine. I have 1TB of games I've installed and all play fine. But here lately seems like things won't install like they did. Any help would be appreciated. Anyone else experience this?

Just to rule out the obvious, since I don't see it mentioned. You have re-dumped your title.keys and your prod.keys since updating to 19.0.X, right? I can imagine that old and outdated keys lead to crypto errors during certain operations. It is pretty much the first thing I do after updating my firmware.

Actually, I have not done that. I guess not so obvious to me? lol. Please explain and I'll give that a try. I've never had to do anything (that I'm aware of) with title.keys and prod.keys. Thanks for the help!
