1. Check the PEB for the Entry Point
The Process Environment Block (PEB) contains information about the loaded executable, including the entry point. You can find this in the dump:
Open the memory dump in IDA.
Locate the PEB structure in memory (usually at fs:[0x30] in 32-bit processes or gs:[0x60] in 64-bit).
Find the ImageBaseAddress and EntryPoint fields.

Maybe I am missing something (or everything), but when I load the memory dump into IDA, I see the following:
