Thank you for your answer, I'm gonna go and try to do the same crash as before

@Old Bruce, I'm okay with this fact but, I mean, with my professional work, I cannot continue like that and remake my layers that I've been working for hours just because they disappeared or glitched, if so, Affinity photo isn't a safe solution anymore Like this isn't the first time this is happening for me, I just wonder if I'm doing something wrong (maybe too many layer, file too big, or idk what) And if I can't get any answer to this issue, I might have to switch to another software...

Thank you @LeeThorpe and sorry for my late answer. I'm saving my file to an external hardware directly connected to my computer I have checked for the crash report, but couldn't find the good one I'm not sure of the method, how could I "recreate" it if I delete it in the first place ? Anyway, am I the only on to who this happend ? and how could I prevent this from happening in the future ?

So, this is what happend : I was working normally on my project, and when using the flood fill tool, it started getting laggy So I tried to save my file before it could potentially crash and then it gave me this message : "not enough space to save the file must now be closed (something like that I don't quite remember" But that actually make no sense at all since I had over 600Go left on my hardwire But there's the real issue : When opening back my file, I found that many layers were randomly gone (at least it looked like it), erased to be clearer, (I couldn't find these layers in the layer tab, and one is weirdly glitching : If I zoom and dezoom, the layer start doing weird things. (The layer is called "Details Arm" on the file attached) This isn't the first time this is happening to me, but the first time, as I wasn't too far in term of progress, I've just started over. Here are some additional info : - I'm using Affinity photo 1.10.5 - My computer : Mac mini (M1, 2020), macOS Monterey version 12.4 - I've tried to restart Affinity photo, my computer, duplicate the file, delete-undodelete and nothing worked And I'm wondering if the glitching layer will do the same thing on your computer, I've attached my fileFemale Space Character.afphoto 1533830200_FemaleSpaceCharacter.afphoto
