SW2024 freezes forever if I add 2nd drawing sheet and save.

Solidworks 2024 sp5.0

 

I've had no freezing issues on this version of SW when saving drawings, until now.

 

One particular drawing I had started with 1 drawing sheet and saved, near-instantly. (Fairly small simple assembly)

Later I returned to this drawing and added sheet 2,3, and 4. I tried to save and SW froze for 30+ minutes

until I finally closed the program.

 

This kept happening after trying every fix recommended:

-changing the detailing performance

-ctrl Q rebuild

-restart

etc.

But the drawing would freeze every time I tried to save it (still with 1 drawing sheet, as the additional sheets didn't save).

 

I tried Save As but SW froze before any dialogue opened.

I tried Pack and Go but SW froze in the saving process.

I tried copying and pasting the file into a temporary folder, opening in detailing mode - this saved successfully.

I tried copying and pasting the file into a temporary folder, opening in lightweight mode - this saved successfully.

I tried copying and pasting the file into a temporary folder, opening in resolved mode - this saved successfully.

So at this point I thought I'd fixed whatever was going on, since I was now able to save the previously un-saveable file.

However, if I even try to add just a 2nd drawing sheet (blank), the file becomes un-saveable again.

 

Why would SW have such a problem with adding one blank sheet?

It seems the problem is therefore not in the geometry or references, but something in the number of sheets.
