General flashback is caused by incompatibility between software and system, and flashback repair can't solve the problem. My idea is to download it again, which can be downloaded on synchronous push. The above resources are genuine licensed software, which will have high stability and compatibility, and basically will not flash back. Many of my previous softwares have flashed back, and now the software that has been pushed and downloaded at the same time has not appeared this problem again. The point is that they can be downloaded for free.
