Bug description

Hello everyone,

Virtual File Support is enabled by default. Renaming subfolders within E2EE-encrypted folders fails to work as expected. The problem often occurs when multiple operations—such as renaming, syncing, or adding files are performed in quick succession. These actions can disrupt the encryption metadata, potentially leading to corruption or complete failure of the E2EE feature.

Note: In some cases, simply renaming the encrypted folder can help restore it to a less severe state (syncing other files resumes) .

I did not notice the issue when Virtual File Support is disabled

Steps to reproduce

Enable E2EE and create encrypted folder
Create a subfolder within the newly created encrypted folder
Allow deskop client to sync the new folder
Rename the subfolder to any new name
You can see that renaming fails and old name persists

Now, repeat the above steps, but this time add files within the subfolder before renaming it. After performing a few sync operations and renames, you will notice that the client fails to sync and e2ee becomes corrupted.

Expected behavior

Rename files at the encrypted folder top level (works)
Rename files within subfolders (works)
Rename subfolders (now fails)
Rename the encryted folder itself (now fails)

I ran into the same or a similar issue. I had disable end-to-end encryption and reset the keys to get end-to-end encryption working again. The issue got triggered after deleting a single file in an end-to-end encrypted folder. Unfortunately, I didn’t find this Github issue until after I had reset everything.
