Crashing on ios

[kaserdan]

Describe the bug
We have started using Kache for out iOS app intitialized by

val dirURL =  NSFileManager.defaultManager.URLForDirectory(
   directory = NSCachesDirectory,
   inDomain = NSUserDomainMask,
   appropriateForURL = null,
   create = true,
   error = null,
)?.standardizedURL

val dirPath = dirURL?.path?.let { "$it/${KtorCacheProvider.CACHE_DIR}".toPath(normalize = true) }
            
KachetorStorage(
   directoryPath = dirPath ?: error("Cache directory path is null"),
   maxSize = 1000 * 1024 * 1024, // 1000MB
)

After a while, iOS app starts crashing and we can't find any way to reproduce this, but we have following stacktrace:

We are having the same issue along multiple API requests. kfun:kotlin.String#<get-length>(){}kotlin.Int + 0 (String.kt:37) called from iOS.

Integrated via Kachetor 1.0.0 which uses Kache version 2.1.0-beta05.

I can't reproduce the issue, so I can't try out if updating to the newest 2.1.1 would solve it - but I didn't spot anything related in the changelog: https://github.com/MayakaApps/Kache/releases

What looks suspicious is that we perform multiple API requests at once and this error appears on multiple threads - could this be a threading/mutex issue? 🤔

@kaserdan Did find out anything further or could you resolve it on your end?
