I opened file and after CTRL+Q feature tree is red and yellow.
First error is with cut extrude option and it says “the feature cant cut the body” .
I cant add any new features because of same error.
Same file on another PC - no errors 
Any ideas what went wrong?
Pc’s have same confogurations and same SW settings.
SW 20221 SP3
Try flipping the direction. The arrow indicating cut direction is pointed away from the body.
… because in these terribly ambiguous situations that is the most helpful direction to cut.
Sketch is on the other side (face which is not visible)so direction is ok.
Anyhow it does not work in any direction no matter what depth i choose.
remove “link to thickness” and select “through all”.
Should fix your issue IMO
I tried , with all possible options.
I tried to recreate feature.
SW says NO
Oh, excuse me, I hadn’t read that it works on one PC and doesn’t on another.
Have you tried resetting the SolidWorks registry and then reloading SolidWorks settings?
Yeah i probably should.
Not me , but my IT 
Alin, or Javelin Tech, has a very nice summary of how to process, if you ever feel like doing it yourself.

If that doesn’t work, I’d look to see if you’re running the same driver for your graphic card. Perhaps you have a faulty driver and the other one has the approved one.
I missed that as well. My only suggestion would be to reach out to your VAR.
I missed as well. It’s just habit to assume that SW flipped the cut direction.
On the problem PC, can you try logging in as a different windows user? When the behavior seems to be local to one PC I ask that user to test same thing on another PC and the user from a PC that doesn’t replicate the problem to try it on the problem PC. Then I know if it’s the user’s roaming profile or PC.
Has one computer got verification on rebuild active and the other doesn’t?
As i said , all settings are the same.
PC is same.
Driver is same.
We will try to reset settings (i dont have any permissions , so that is why IT must), and probably we will contact our VAR
Are you sure the sketch is closed? As a test, try to extrude it.
I can vouch it’s closed. Sketch lines do not have the same thickness for open profiles. They become “as thick” as construction lines.
Yes , and i dont believe it would work on another PC if sketch is open
I don’t do much sheet metal work, so these are just guesses. Is there an add-in that could be missing from one computer? Or a feature that isn’t turned on?
have you tried normal cut?
Yes.
Unfortunately it wont work.
Biggest suprise to me is why this part is loaded normally at PC’s of my colleague who have exactly same settings as me, and on my PC it shows red feature tree.
Have you tried bnemec’s suggestion of trying on your PC with a different user then yours..?
