I then tried to uninstall it manually, only to find that the uninstallation failed; overwriting it with a fresh installation didn’t work either. I had to perform a forced uninstall using a third-party software. To reproduce the issue, I reinstalled version 147.0.3 (both the Simplified Chinese and English versions), yet the problem persisted—the full installation process could not be completed. I had to perform another forced uninstall via third-party software. After installing version 146.0, the issue was resolved. Therefore, please have the developers look into and confirm this problem.
