I don't know why my file takes > 10 min to open.
The short answer is that you're making a hidden line drawing and every face and edge in every one of those individual components needs to be compared to all the others to determine if it is visible or not. In version 0.20 all those comparisons are done sequentially. In v0.21 many are done in parallel, so it loads a lot faster. Interesting, but not helpful.
You're not really interested in the objects behind the ones you can see, so it makes sense to not include them in the drawing. I used some judicious selection to make
this file. It loads in about 2:30 here vs >10 minutes for the original.

And when wanted to open an "old" file created earlier all horizontal lines break - 2D_left_Rack_80_200
Horizontal dimensions between vertical tubes should be 0.82 m.
I'm guessing, but I would say there was an edit somewhere that changed the numbering of the edges associated with the dimensions. Some of the horizontal dimensions are now linked to vertical members. This is an aspect of the dreaded "topological naming problem".
