Global slowness on CI, simple test like clicking on a component taking from 20s to minutes

Hello, I have a moderately dense GUI, I'm looking for specific reasons why simple command lasts at least 20s on GitHub Actions, some taking minutes for one click :
```java
@Test
void shouldFindInjectionPreferences() {
AppUiTest.window.checkBox("checkboxIsParsingForm").click();
AppUiTest.window.checkBox("checkboxIsParsingForm").click();
}
```
All the tests are instant on local ([source code](https://github.com/ron190/jsql-injection/blob/master/view/src/test/java/com/test/assertj/AppUiTest.java), [GH actions logs](https://github.com/ron190/jsql-injection/actions/runs/12897417664/job/35962486935)), the entire test suite in this file lasts 59s in local, and it lasts 2h16m on GH actions.

Is there a problem about lookup by name ? about EDT ?

Is there any ways to speedup one click in some ways ?
