Crash when open directoy with @ sign

[Offerel]

Describe the bug
On my SFTP server, i have folders where the name of the folder contains an @ sign. If i open this folder with Amaze Filemanager, it crashes.

To Reproduce
Steps to reproduce the behavior:

1. Create SFTP connection
2. Open the connection
3. Open folder
4. Open folder with a @ sign in name
5. App crashes

Expected behavior
Folder can be opened

Smartphone (please complete the following information):

• Device: Galaxy S23+
• OS: Android 13
• Rooted: [No]
• Version: [3.8.4]

Additional context
If I create a symlink to the same folder, without the @ sign, i can open the folder. I don't know, if other signs are effected also.

Update: When i manually enter the directory name and us %40 instead of @, i can access the directory. But clicking such a directory leads to a crash. I have no skills in Java programming, but i assume, the filenames should properly urlencoded. Then it should work.

Should be fixed by #3661 for 4.0. Let's see it.

Is there any release or pre-release date or can be downloaded from github actions?

Many thx. After testing, my issue with the @ sign is solved in this version. But a other dorectory is listed as empty. If I look at the server, this seems to be a bind mount. I'm not sure if this is responsible for not displaying the directory content. I will try to find the reason tomorrow.

Other file managers like Solid Explorer and Material Files can list the content of the directory. I will report if I find more info.

Additionally hint: when I download a file via SFTP (SCP is not allowed there), the speed seems to be slow. I get around 4MB/s, the same as with Material Files. With Solid Explorer and the same connection and file, i have around 8MB/s. I haven't tested SCP for now.

I have found more. Its not this special directory. If i open this directory directly after logging in, all is fine. However, when i have accessed a folder with this new version and i go back or up a directory, this appears as empty. All folders appears as empty, when i go back or up one level. Maybe its only a listing-refresh issue?
