wise imagex Face Swap feature throws "FormatException: Control character in string" error since May 27, 2026

[darkos]

Hello WiseCleaner team,

I have been using **Wise ImageX** and encountered a recurring error when trying to use the **Face Swap** feature. The issue started on **May 27, 2026** and persists until today.

**Steps to reproduce:**  
1. Open Wise ImageX.  
2. Go to **Face Swap** from the sidebar.  
3. Upload a valid source image (clear, recognizable face/mouth).  
4. Upload a target image (also clear, max 10 MB).  
5. Click the **Generate** button.  

**Result:**  
The process fails and shows the following error message:  

> `FormatException: Control character in string (at character 203)`  
> `...RequestOptions.validateStatus was configured to throw for this status code.`

**Expected behavior:**  
The face swap should complete successfully and produce the output image.

**Additional info:**  
- I made sure both images are within the 10 MB limit and have clear facial features.  
- Other features like Restoration, Colorization, and Remove Background work normally.  
- The error appears consistently every time I try Face Swap.  
- My system is up to date, and I have reinstalled the app – the issue remains.

Could you please look into this and provide a fix? Let me know if you need any logs or sample images from my side.

Thank you for your support!
