Is it permissible to deposit money in the Islamic transactions branch of a usurious bank, knowing that this branch does not specify a profit percentage and expects a loss with state guarantee?

It is permissible to deal with the Islamic branches of interest-based banks if their dealings are free from prohibited transactions, while ensuring that their transactions comply with Islamic Sharia. One of the permissible forms of investment is "Mudarabah," where the capital comes from the client and the work from the bank. For it to be permissible, there are three conditions: that the bank invests the funds in permissible activities, that the capital is not guaranteed so that the client bears the loss, and that the profit is specified and agreed upon as a percentage of the total profit, not of the capital.
