I have a bug. I’m trying to delete a deck from my anki desktop and when re-open the app, anki says:
“Notes found in file: 118
Notes added from file: 118”
and then the deck is added to anki.
I tried to create a new profile and new account, but the same issue persists.
I tried to delete every card from the deck, but still the same thing happens once I re-open the app.
That sounds like you are double-clicking on an .apkg file, which opens Anki and imports the file into it.
no I’m not doing it, I could upload a video showing what happens but I cannot include links 
The process was as follows: I uploaded a text file from notepad, then deleted it and uploaded another one based on the first one, just added more words and changed the word order.
How do you open Anki?
I’m pretty sure you’re double-clicking on a file, instead of double-clicking on the application itself, which causes the file to be imported.
