Hello
My Solidworks 2026 was working correctly since its installation in December 2025, but for the past 3 days it has been indicating a lot of errors when opening assemblies with which I had no problem before.
some even don't want to open anymore SWSHEL error 1.
Can you help me?
Kind regards.
Try copying the head of your assembly and reopening it, on or off PDM.
Hello
Have you attempted a repair?
2026 SP0.0 don't really surprise the bugs

Hello Stéphane. My answer won't please you. This is not a solution, but a potential explanation.
NEVER EVER, INSTALL a recent version labeled from the year of grace where we are. Always stay on an year -2 and sp3 version at least evening 2023 or 2024.
It's a rule of life. I hope your problem will be solved quickly.
Good luck.
On my side I didn't have a choice during the mandatory update under 3DExperience, sp0.0 automatically, I didn't have any big notable bugs
