Hi @stforum @stforum2 @Mahmoud Ben Romdhane
Good evening.
I am working on an STM32F765VGT6 microcontroller using STM32CubeIDE v1.19.0 on Windows 10 Pro. The project requires enabling both Ethernet (ETH) and USB Custom HID functionalities.
On 22 July 2025, I received an email from the ST Community recommending an update to STM32CubeIDE. At that time, I was using v1.17.0, and I proceeded to update to v1.19.0 as advised.
Problem Faced:
Today, I encountered an issue where the middleware files related to LWIP and USB HID became corrupted, even though I was working in a different workspace.
Due to this corruption, I am unable to restore my previous working code and also unable to access Ethernet and HID functionalities.
This issue has occurred after updating to STM32CubeIDE v1.19.0.
Now neither i can get back older version of code nor creating a new one which is working.
Request for Assistance:
Could you please advise on how to resolve this issue? Specifically:
How can I repair or reinstall the corrupted middleware (LWIP and USB HID) components?
Is there a way to recover the middleware in existing or new projects?
Should I consider rolling back to an earlier IDE version (e.g., v1.17.0), and if so, how?
Thanks & Regards,
Manogna V
