My burp version is the 2020 version
I could open it before, but suddenly I can't open it today.
I checked online and found that some people have also encountered this problem. They said it might be a problem with the Java version.
I tried to check my Java version, it was 1.8
After changing my Java version to 11.10, burp can be opened normally again.
A false alarm~
