Forge server couldn't start, pls help

[AKappaGG980]

Game version is 1.16.5, no mods were installed, using Java8 while it happened. And I have multiple different versions of Java including Java8, 11, 12, 13, 14, 15, 16, 18 were installed in my system, but there is only Java8's path inside the environment variable. Could them be one of the reasons? I'm new here so I almost don't know anythings about forge server. Please tell me if you need other files or logs.

Following is the output inside CMD after I open the "start.bat":

ECHO 处于打开状态。

How exactly did you install the  server? Show a screenshot of your mods folder.

I don't have a mods folder, above is the photo of the folder where the server is.

[AKappaGG980]

I downloaded the forge installer, choose the "Install server" to this server folder and wait a few hours to let it download files, after it finished, there were only "libraries"folder, "forge-1.16.5-36.2.35.jar"and"minecraft_server". Then I double clicked the "minecraft_server.1.16.5.jar", the "eula.txt" and "server.properties" appeared without any window, I opened eula and turn the false to true. Then I write a .bat file. Its content is:

@echo
"C:\Program Files\Java\jre1.8.0_321\bin\java.exe" -Xms2G -Xmx2G -jar forge-1.16.5-36.2.35.jar nogui
pause

I save it and opened it, CMD showed the error code in the top post.

[AKappaGG980]

I live in China, It's very slow when connect to international internet, I really using at least 2 hours to wait it finish.

And can you tell me where the installer log is?

[AKappaGG980]

Sorry mate, I can't find it. Maybe I deleted it while I was tiding up my desktop during the waiting… I will try to reinstall it to get another log, and hope it will be faster then last time.

[AKappaGG980]

It can work after I reinstall it! But still thank you diesieben07 for trying to help me fix the problem：）
