After updating to Eclipse 2020.12 most icons from Views are turned to red squares every time I restart Eclipse (screen 1). They turned back to normal when clicking on them (screen 2) until next restart. Any way to fix it?

How was this update done, and what release are you coming from? You have perspectives that used to be there acting like they're no longer installed.

Thanks for the reply.

Update was done by installing new the version of eclipse into the new folder.

Previous version of eclipse I've used was 2020.06 (4.16).

I know that it looks like so but it is not the case I've shown on the screenshots the behavior: view icon appears when view clicked and that works for all views with red icons but all icons turns red again after eclipse restart. And this bug affects built-in views as well (for example Breakpoints, Variables, Expressions etc. views are affected). I've made a screen collage to show the problem on one image.

I've checked the workspace log files and there are a lot of FileNotFoundException about .gif files, like this:

java.io.FileNotFoundException: /icons/full/eview16/debug_view.gif

So after 3 hours thrown at restoring workspace from backup and reinstalling Eclipse several times I think the problem is that the Eclipse 2020.12 incorrectly upgrades workspace to the new version.

I've managed to fix this by using Export->Preferences in previous version of Eclipse to export my workbench and reseting workbench (delete workspce\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi ) and using Import-Preferences to restore workbench from the file in the new version of Eclipse. Now it works as it should.
