I just got it in 8.1.43, but my quick fix was to right click and click "close and revert". I have a hypothesis that if any of your page URL might have an error or the page config have any errors that it affects the other views. I had just made a new view that didn't have a correct page URL structure and when i deleted that view and clicked "close and revert" it got fixed.

Just had similar in Designer for Ignition 8.1.43 as well. I followed @Petter_Sunde_Vegsund 's approach of close & revert for each of the views I had opened since last save, working backwards and attempting to save each time. On the third try I noticed a view had not loaded properly on open - the usual edit viewport was just blank white. After close & revert on that one, the project saved fine.
I do remember accidentally opening that particular view and immediately attempting to open a different view, so that may be where the error occurs?
Given how compulsive I am with Ctrl-S this wasn't a huge issue.
Upgrade to 8.1.44. This release has a fix for this and I can confirm it solved the issues I had.

for my case, I open that page with user link, http://your link
if the link can display as normal, then , you go back to Ignition designer perspective open that view.
The view will came back as normal.

i may have found a solution,
when this comes close the designer and go to gateway--> projects and export your project
now comeback and create a new project in designer and import the project that you exported
(pray for couple of mins) 
then open any view that was throwing this, it worked with me once
Are you suggesting that you are still having issues after upgrading? The 8.1.44 release had a fix. If you are still seeing issues then you should contact support so they can take a closer look.

No , our whole team is using 8.1.35 , so we are sticking to that version
That seems unwise. Is there a reason other than convenience?
