I found this Database Repair Error: no such collation sequence: icu_root which states you cannot use the normal sqlite3 which goes against the instructions in their own article I posted above. So I went through those processes using that information but it did not seem to help – STILL CRASHING. Although it did remove the errors I got with the sqlite3.exe I tried originially. Here is that output.
