SUMMARY
Large resolution .kra file with lots of layer styles sometimes become unopenable after saving
When I open said files, the software may freeze for a while and then simply abort loading like nothing ever happened, or just crash
Allocating more RAM for the software doesn’t fix the problem
The file becomes openable again after manually deleting a huge layerstyles.asl in the .kra file,

STEPS TO REPRODUCE
Dunno how to reproduce exactly
But if you use a lot of layer styles on very large canvas it would happen from time to time
For me it happened twice

OBSERVED RESULT
.kra file becomes no longer openable after saving, but deleting a huge layerstyles.asl in the .kra file (by opening it as a .zip) makes it openable again (naturally losing all layer style settings but otherwise still good)

EXPECTED RESULT
I expect .kra files with large resolution and multiple layer style settings to load and save normally without having to tweak the file as .zip

SOFTWARE/OS VERSIONS
Windows 11
Krita 5.2.6

ADDITIONAL INFORMATION
The .kra file is rather big (200 MB) 
So here is the abnormally large layerstyles.asl file extracted from the .kra (over 1 GB when extracted, compressed into a 6.6 MB .zip file)
Your website does not accept >4000KB files so here is the catbox link for the file: https://files.catbox.moe/gv0mjs.zip

Added the correct software, Krita, and version of Krita to the report.

I, myself, can not confirm having this issue, although I use and used layer styles a lot, and for a long time over many versions of Krita, regular releases as well as nightlies. I used both types, original Krita layer styles in ASL format and also Adobe ASL's extensively in the past and can not remember issues.
