Instruction:
First, you must have the tools listed below
1. A hex editor (HxD is preferred)

2. Vexorian's Map Optimizer (can be obtained from this forum)
After the tools are prepared, you have to open the map using hex editor, then search for line 1F0, highlight that line and drag it to 7E0, delete line 1F0-7E0. Next, using Ctrl+F type 4D 50 51 1A, remember to set Datatype as Hex-values
Spoiler:
Fix the line with 20 00 00 00 15 40 45 50 00 00

Finally, process the map using Vexorian's Map Optimizer (with all options unticked)
NOTE: You may get an I/O error, I got no idea how to fix it, but don't worry, you are done. Now you can open the map with MPQ Editor, MPQ Master still crash though.
Thank you for reading, any comment and idea are welcomed.
I'm using this map for demonstration:
