The crashes are happening constantly, but the hardware has been tested and everything is okay, as shown in the image above.
There are many instances of freezing when opening any Flatpak file, such as YTDownloader, Signal, and others.
Perhaps my machine is too old and it’s time to replace it, but I also use OpenSUSE TW on the same machine with a different hard drive and I don’t experience the same errors described in the Fedora 43 problem report. What intrigues me are the BTRFS error messages, but the hard drive has been tested and is OK.
