It turns out that the version 24.1.0 is very buggy and should not be used. Many patches came afterwards. I tried my models with version 24.1.6 and they worked again as they should.
Notice that there is a warning in the official site:
WARNING:
The recent versions of LTspice for Windows (version 24.1.*) are a significant change from previous versions. Any major program revision such as that can be subject to all sorts of problems, and this is no exception. Analog Devices has worked hard to fix new bugs. Also, some of LTspice's behavior fundamentally changed, which may cause a few older simulations to work differently, or not at all.
I hope I saved some precious lifetime to someone out there. ♥
