What is the best debugger for assembler?

Question

assembler

Good day!
Please recommend the best debugger for a beginner who has just started to get acquainted with assembler. Of course, the batch debugger with its creepy 30-year-old ms-dos look is no good.

I tried to open the first executable file through x64dbg, I got a message that I was trying to open an invalid PE file (moreover, everything is somehow strange here - some .exe open, some do not). I started looking towards OllyDbg, but its development stopped a long time ago - 10 years ago. Delivered, immediately received a message in the forehead about the wrong bit depth. True, I heard that he has some forks, but I don’t know at all where to start and where to get them. I became interested in IDA Pro, but from the description it is clear that this is a disassembler, which has slightly different tasks.

I have win7 x64.

Thanks for the answer.

For 10 years nothing has changed (I mean for x32).

This happens when you open x32 PE file in x64 bit version of x64dbg or vice versa.
Look carefully - x64dbg has x32 and x64.
If you are studying x32 - then take OllyDbg (or x64dbg x32). For many years, a lot of guides have been written on it, + a series of lessons (it was somewhere on wasm).
If x64 then x64dbg.
