[Bug]: FormatException: Invalid Zip Signature

[lengerke]

What happened?

I cannot open one specific file anymore that I worked on. Before the file was corrupted, there was a significant delay between the stylo touching the display and the app drawing the corresponding line (up to several seconds). The tablet was otherwise responsive and I worked offline. I don't know if that is relevant, though.

Version

2.2.1

Platform

Android

Hmm, looks like a duplicate of #746 but I really don't know how to reproduce it.
Looks like a bug inside the zip library that I use. I'm always happy for contributions or reproducible steps that I can test.

Did you have used any "non-ascii" names? Maybe this could be the problem: brendan-duncan/archive#354
