I worked on a project since some hours now and saved it normally yesterday. When I tried to open it today, I just got a message saying:

"The image contains pixels with zero alpha channel and non-zero colour channels. Krita has modified those pixels to have at least some alpha. The initial values will not be reverted on saving the image back.

This will hardly make any visual difference just keep it in mind."

After that, Krita seemed to try and load the file, but just... closed. No error message, crash report or anything. I've looked through a lot of "Krita chrashed" forum entries, but non of them seem to apply to my situation.

Thanks in advance for your answers!

Sounds like you're not working with .kra files but with .exr files?

Oh yes, seems like it. It normally always saves with .kra.
So is this a common problem?

No, there's nothing common about this. You're doing something weird and strange, and haven't really explained what you are actually doing.

Does Krita crash with your other .exr files? If not, and only this one, can you please share this file with us somehow?

Where did you get this file?

Remember to always save as .kra if you intend to work on that file again - you can save in two or more formats, of course, but it's best to always save as .kra as well to make sure everything that you cna do inside Krita is saved to the file.

@boudewijn Appreciate you. I work for customer service and I know how it is to help people who have no idea what they are doing. That said: I have no idea, what I did wrong.

This folder has two files. "Mutatedeye.exr" is my project. "Test1.exr" is a project file with two layers, some colours and a visible alpha background (just erased layer 1).

"Mutatedeye.exr" doesn't open, the "Test1" does.

Well, thanks, that was helpful.

Please report it on bugs.kde.org and someone will catch you on that at some point. Please attach your file that crashes Krita. It's hard to keep it up on a forum sometimes :/

With krita 4.2.8, both Linux and Windows versions, I can open both of those files (with a warning notice as you mentioned) and then save them as .kra files which then open with no problem,
I can also make changes and save as .exr files or .kra files that will then both open with no problem.

Which version were you using when you first had this problem?

Sorry for being passive-aggressive earlier. I just read the pinned post on the Krita-Reddit; you guys don't have much time for all the questions. ^^'

Anyways, it seems to have been a compabilty issue. I just downloaded the .exr-file onto my new laptop and it works just fine with the newest version of Krita.
Unfortunately I can't access my old PC (where it didn't work) right now, so I can't really tell you much about its software or hardware.

There also just aren't many guys (or gals) to begin with. Adobe, we ain't
