STM32F030 Data mismatch error

[MuratHepeyiler]

Hi, I am facing up Error: Data mismatch found at address error. I have tried to decrease the frequency, also make a modification to the linker script. Also, I used OCD. But, no success. When I open a new project it uploads. Whenever I change something in code, it goes even if I change to back the code. Could you help me?

I am working on STM32F030C8Tx, and using stm32f4-disco st-link. As a programmer STM32CubeProgrammer v2.4.0 and as an ide STM32CubeIDE Version: 1.5.1 Build: 9029_20201210_1234 (UTC).

Quick update, I have upgraded CubeIDX(v1.6.0) and CubeProgrammer(v2.7.0) to the newest versions The problem is still. Then I used Keil uVision and everything worked perfectly.

Also, good to mention that, below case happened. Same code, same chip, same programmer. Just the difference 84sec.

Also, I have tried the same code upload keil uVision and STM32CubeProgrammer.

I really like to use the STM32Cube environment. However, this bug pushes me out of it.

@Imen DAHMEN​ if it is possible, could you check it out? I think there is a bug.

By the way, I have taken a sample using Logic Analyzer and WireShark during upload code. If you like, you can find the zip file below the link. I am using KingstVS device, thus I have added .vis, .csv, and Wireshark capture file.
