if according to the above delete a file or can not open the UI file, it is only a possibility, your computer's graphics driver is the latest version, the QT is not compatible with the UI display, it is recommended to uninstall the latest board driver installed stable version......This problem has been bothering me for 2 weeks, reloading in the middle. Or for countless versions of QT also according to the upstairs said to delete the file is not good, so into the debugging mode to debug the program, read the newspaper after the error check is. Show the problem, so uninstall and reinstall the driver. Then I had to open it. Write down the method for future generations to see
If it still cannot be opened, you can install the latest version of Qt5.15.1(online install in attachmen).
