Cannot download project to target but IDE inform completed

[_binhvo1003]

Hi, 

I have an issue with my Nucleo-F446RE. There is a big project from my client, I already download it to target and it runs perfectly fine. But on tomorrow, when I perform a download of my Test project to the target, then I re-download the project of my client. The IDE still not appear any error and inform download complete but the target cannot get the download anymore, there is still my Test project in the board. But the strange thing is, I try to download another project and it still fine, so just my client's project has problem. But it is still can download before.

So do anyone meet this situation before? Please help!!

The customer application CubeIDE upload is OK but the application doesn't run?
