java.lang.NoClassDefFoundError on First Launch After JAR Update

[lzpzywoo]

I encountered an issue after updating the JAR file in my project. Upon the first launch after the update, I receive the following error:

Caused by: java.lang.ClassNotFoundException: com.doorun.uploadreport.HospitalNetworkInfoApp
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(Unknown Source)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(Unknown Source)
at java.base/java.lang.ClassLoader.loadClass(Unknown Source)
... 13 more

However, if I close the application and restart it, the issue does not occur, and the update works successfully. Additionally, when running the application in IntelliJ IDEA, I do not experience this problem during the update process.
