missing sqlite.interop.dll

I'm extrapolating from sparse input here, so more detail would help if this surmise is wrong: I suspect that you have attempted to use a SQLite.Interop.dll that was built for the Intel/AMD x86/x64 CPUs rather than for Arm CPUs. (And the DLL is not really "missing" as your thread title suggests; it is not loadable and the one that would be loadable is not yet present.)

I do not know where you will find the Arm-targeted DLL already built. You may have to build it from source.
