Why doesn't pyinstaller add the db when converting to one file?

Question

Python

Hello everyone
When I convert .py to .exe with "pyinstaller -w --add-data "server.db;." main.py" everything works as it should, but if I want to convert .py to one .exe file without all these dlls and other things, i.e. I write "pyinstaller -w --onefile --add-data "server.db;." main.py" , the program logic works as it should, but the database is not added, what could be the problem, please tell me?
I'm using Sqlite3

UPD: when compiling with one file in cmd, I get the error "Unable to find "C:\'path to file\server.db'" when adding binary and data files"

UPD2: I also tried the method "--paths C\path to file\server.db", which also did not work
