Frequent crashes after update to Fedora 39

I have updated from Fedora 38 to 39 yesterday. Since then, I am having frequent crashes where the screen goes black for a couple of seconds, then goes back to the login page, and after I enter the password all applications are closed. No mention of the crash appears in the notifications. This occurs randomly, after maybe 5 minutes of use, not in connection to anything specific that I am doing. I tried booting both the current kernel 6.5.11-300.fc39.x86_64 and on the previous kernel, namely 6.5.10-200.fc38.x86_64, but both have this problem. I don't think that this is related to a hardware issue because Windows, in dual boot, runs ok, and the freezes only appeared after the Fedora 39 update. The computer is a Dell laptop. The graphics card is the integrated Intel one. What can I do to find the cause?
