It still has the same defect, after the macOS installation is finished, the mac crashes the startup bar, shuts down, and speeds up the cooler.

Should be problem with some driver.
Check in system report if all devices are correctly listed.

Check if the machine boots in normal mode without battery.

Inspect U6300 area, on both sides; possibly corrosion issue.
Check the small coils from its power rails.

LA950 and LA950 get very hot.
I replaced the u6300, but it is still without a driver.
It seems that there is a GPU defect because it showed a report.

GPU failure was expected, but was strange to found it enabled and working in safe mode.

The report points to GPU issue indeed.
