Any recommendations for LZWDecode code

Got a Pdf1.1 file here which is crashing my win11 machine when loaded in MS Edge as the viewer.

Its pdf version 1.1 and mainly consists of multiple LZWDecode blocks so trying to find out why its crashed.

A quick search for MZ[null] doesnt show anything in notepad++.

Theres no flatedecode to compress/obfuscate that I can see so curious why it crashed.

Dont know if this is a problem with MS Edge, Win11 or some hardware setting.

So I guess first plan of action is to pull out these data stream objects and see what they show.

Hence the question.
