Problems with Mercedes C-Class diagnosis after database update

I own a Mercedes C-Class (W203, year 2004, gasoline, 160,000 km) and have the following problem: Since the update of the Mercedes database to version 45, diagnosis is no longer possible. The control units have implausible names and only internal DTCs are displayed as DTCs. Everything worked correctly with the previous database. Has anyone else experienced the same effect or found a solution for this? In addition, the ABS/DSC system is not working. I would appreciate any help or hints!

For the diagnosis issue, try reverting to the previous database version if possible, as it was working correctly before. For the ABS/DSC system, check the ABS fuses and relays first, as these are simple checks. If the problem persists, it could be a sensor or wiring issue. Since ABS is a critical safety feature, I recommend having a professional mechanic inspect it. Let me know if you have any updates or further questions!

Is there a guide on how to revert the database version in the app back to version 44? Even if I reinstall the app, I have to upgrade the database to version 45. The app doesn't allow anything else.
