Electron/Javascript App causes data loss with Cryptomator

Hi, Im using Cryptomator 1.6.5 (win) with Dokany 1.5.1.1000. With one specific App MarkText - Electron/Javascript App there is a strange behavior, which doesnt occur with Non-Cryptomator-Folders.

It seems the app code tries to check, if the questioned file exists, but can not find it. Cause of the failed check, the copy-function causes a data loss and the “Delete”-Feature doesn’t work at all.

Does anyone have a hint for the Devs of the project?
