Error while opening the catalog

[franks21504871]

Since today after updating to the latest version I keep getting the following error message on my screen. After restarting the computer Lightroom can be opened once. If it is closed I can't open it again because of the error in the screenshot. Creating a new catalog or opening another one also causes the same error.
