Androidstudio failed to create Jvm:erroe code-4 problem

After months of not touching Android studio, the error occurred when you opened it:

I'm a Pepsi! The last time I used it was good, and now I'm saying I have a problem with my Java environment variables. I look at the environment variable also no problem ah, so there is only Baidu. The last problem is solved, although I don't know the reason.

Baidu's Solution:

A buddy met the same question as me:

Someone else gave him a reply:

This means that the Studio.exe.vmoptions file is found under the bin of the Android Stduio unpacking package.

After opening, change-xmx512m to-xmx256m,-xx:maxpermsize=250m to-xx:maxpermsize=128m.

or change-xmx750m to-xmx512m,-xx:maxpermsize=350m to-xx:maxpermsize=250m.

After the change, you can start normally.

What the hell is this?

Why does Android studio not report this error for a while? What is the basis of this approach? The problem has been solved, but I want to get a clear idea. If a great God sees, ask for guidance.
