OK, so it is a runtime error. This is more challenging for me to assist with than a compilation error as discussed in Sketch compiles on Arduino laptop IDE but not web IDE - library issue? because I don't own a PeaceFair PZEM-004T module. Maybe one of the other forum members has one and can give it a look.
Runtime errors can also be caused by a new release of a library dependency that either contains a bug or else a change in behavior that requires a modification to your sketch or even circuit. However, it doesn't appear that is the case here because I can see from the compilation output you shared that there is only one candidate library on the Arduino Cloud servers, so there is no chance of ambiguity in which library was used:
This is the "PZEM004Tv30" library used to compile your sketch:
The 1.1.2 version of the library being used was released in 2021 so, unless it was years ago that the sketch was working, the problem was also not introduced through a new release of the "PZEM004Tv30".
The remaining dependency to consider is the ESP32 boards platform, which is also periodically updated on the Arduino Cloud servers. I don't know when that happened last.
I recommend checking over your circuit. I know you did some validation with that simple "hello world" test sketch, but it is still possible an intermittent connection (which are common when using solderless breadboards) could result in a degradation of communication with the module.
