Hi experts
When my customer uses UniFlash 8.8.1 for online programming, the following error screen appears at the start or end of the programming process, prompting "File load failed". Currently, the failure occurs with a probability of about 5%. (The chip being programmed is blank.)
The programmer is XDS100V3.
The complete error message:

Currently, the following methods are used to address the issue:
1. If the error occurs at the beginning stage (when the chip is still blank), simply repeat the programming process.
2. If the error occurs at the end stage (when encrypted information exists in the chip), use a programming project with a password for programming.
3. Occasionally, powering off the device or plugging/unplugging the programmer is required before programming again.
4. In rare cases, multiple reprogramming attempts on the same chip all result in errors, and restarting UniFlash is needed to proceed.
Kindly confirm the trigger conditions for this issue and how to avoid/resolve it. Thank you.
