Lightroom Classic does not open and throws and exception since the last update

Hi,

I have a problem with the new Lightroom Classic update (and Lightroom as well).
Since updating to v15, when I try to open the program, it doesn't launch, but if I open the task manager, I see the process active and it consumes more and more memory until, a few minutes later, an exception message pops up with the following text: "Exception Processing Message 0xc0000005 - Unexpected parameters".
If I revert to the previous version, it works fine.
I tried uninstalling Creative Cloud and reinstalling it again, but the problem persists.
