My-Team Career Mode stuck

Hello. I'm playing the F1 25 MyTeam Career Mode on Steam. After finishing the first season, I wanted to start the new season. Unfortunately, that isn't working. I'm stuck on the screen where I'm supposed to select the engine manufacturer. All the options in the “Owner” and “Team Identity” tabs are checked. In the “Company” tab, the “Driver 2,” “Driver 1,” and “Title Sponsor” options are checked. Next to “Engine Manufacturer,” there’s a red triangle with an exclamation mark. I can’t select the “Racing Gear” and ”Next” tabs. When I go to the “Company” tab, it looks like this: The title sponsor is already there, and I can’t change it. One of the two drivers is also already there, and I can’t change that either. In the field for the second driver, there is only a + symbol, but the field is locked for me. I can’t select it. For the engine manufacturers, I can select all four options. However, it doesn’t matter which of the four options I choose. I can’t confirm the selection. I suspect this is because there is no second driver. I have restarted the game several times and checked the game files for errors, but I keep getting the same error. How can I fix this problem?
