After running the R2025b, the command line operation was fine, but when creating a new script, it would crash and freeze.
Thank you all very much for your suggestions on how to solve the problem. Thank you!
Here is the error log.Its file address is ："C:\Users\zhonglvlin\AppData\Local\MathWorks\_eMqNeOTp3QYuHQHNyIvexNxWu9xERjY-v2vgDyI3AM\crash_reports\reports\2d0df54c-c4f1-4b49-8d92-32935a8c188a.dmp"

Hello ,
Please try the below trouble shooting steps and see if each of them have any effect on the crash:
1) Update to a newer version of MATLAB
2) Download local doc and try to use it
2) start MATLAB with the -cefdisablegpu flag 
3) Start MATLAB in nodesktop mode: matlab -nodesktop
In nodesktop mode:
  a) Launch webwindow:
>>a=matlab.internal.webwindow('http://mathworks.com');a.show
  b) Launch MATLABWindow.
>>cd (matlabroot); !.\bin\win64\MATLABWindow.exe
  c) Launch doc browser:
>>doc
If the crash occurs when opening the doc when using -cefdisablegpu, see if the crash happens when Matlab help is set to offline and Matlab is started with the parameter "-cefdisablegpu"
If the help opens and the home page is fully loaded. However, as soon as you click on one of the hyperlinks to open one of the help articles, Matlab crashes, check if one of the following is blocking the start of MATLAB Window:
  • Firewall
  • Proxy server
  • Antivirus software
  • VPN (Virtual Private Network)
