I don't think that anything will change next season on Barcelona financial situation, because they need to improve their financial strength and that cannot be done within a season. Barcelona needs to find a means in which they can solve their financial difficulties so that they can buy players of their choice in order to strengthen the team.
If the financial problems are to be solved then Barcelona must sell some players who get big salaries from the club but if that is done it might be problematic for the team's journey. Recently I heard about the failed recruitment from Barcelona so that Nico William extended his contract with Athletic Club. This shows how unprepared Barcelona is because they don't have the money to recruit the player even though Nico William himself previously said he was interested in playing for Barcelona.
