The instructions that show in the disassembler are not stable: Executing a "Select current function" on an instruction causes that instruction to vanish, its address now incorporated into a different instruction.
Here's a 10 second video that illustrates what I've encountered:
youtu.be/1nAxXX7F_rw
(I can't post URLs, yet.)
I've never seen this behavior in Cheat Engine, before. What's going on?
The address of the initial instruction was found using the "Find what writes to the address" function.
Note that after the "Select current function" operation the original instruction is gone.

Cheat Engine's disassembler, like all disassemblers just guesses the best it can from some starting point you can select near the instruction and press the left or right key and it will shift and reinterpret the byte code.

Thank you for sharing that tip, TheyCallMeTim13.
I wonder why it is that the breakpoint set at the address identified by "Find out what writes to this address" isn't hit, in this case. Is the address of the instruction identified by that feature reliable?

Yeah, I would trust the why the debugger found it.

Thanks, again, TheyCallMeTim13.
Does anyone have any suggestions for how to deal with situations in which Cheat Engine seems to be guessing the instructions incorrectly? I can set breakpoints one byte backward at a time to identify the instruction boundaries but doing so is time and labor intensive.
Is this the way that everyone proceeds? Or do you have some clever tricks that make this process more manageable? Or maybe you use another disassembler?

Not really, but you can try "ollydbg" or "x64dbg". Other than that it's mostly just trial and error.

those have to guess as well
what you can do in CE, is just press the left/right arrow keys for ce's disassembler to shift by 1 byte
