Slow opening assembly

3D Design

Hello
I'm on SolidWorks 2022.
Since the return from vacation, it takes a lot of time to open certain files.
For example, a file that opened in 1 minute 30 took more than 7 hours to open!
Once opened, the file was saved in less than a minute, which rules out a network problem.
I can't find a solution to this major problem.
Do any of you have this problem?

FYI, in large assembly mode, the file opens quickly.

Thanks in advance

Hello
You can do a performance evaluation once the SSA is open ("Evaluate " menu ). This will allow you to see which sub-assy is blocking or which part file (why not).
Otherwise, once opened in large assembly mode, switch to light mode at first, then resolve.
