Solution

0. My version

apache-jmeter-5.3
jdk17.0.1

1. Try not to use Dark mode

This also includes other problems. As long as there are related fields such as darkfilexxx after the error report, you can directly change the dark skin to solve it. Basically, after this step, you can open the file.

2. Check the environment variable system variable

JAVA_HOME and JMETER_HOME fill in their own installation paths.

CLASSPATH
.;%JAVA_HOME%/lib/dt.jar;%JAVA_HOME%/lib/tools.jar
path added

%JAVA_HOME%\bin
%JAVA_HOME%\jre\bin
%JAVA_HOME%\lib
%JAVA_HOME%\lib\tools.jar

If you do not want to use the .bat file to open jmeter, but use cmd to enter jmeter to open it, the path should also be added

%JMETER_HOME%\bin

3. Add jar package

(I don’t know if it will affect this result. The original intention is to add a monitoring tool plug-in to understand learning, but the fact is that the problem has been solved after adding these two packages) monitoring
tool. After downloading these two compressed packages, unzip them, copy and paste the jar package in lib/ext to lib/ext in jmeter.

So far, the problem of not being able to open the saved file has been solved.

The relevant installation package resources will be uploaded later.
