Different behavior between runIde instance and vanilla instance of IDE

Hello everyone,
I have a different behavior between two instances of the IDE.
With the instances lauched by the runIde gradle task, i don't have any error, but when i lauch the IDE from the jet brain toolbox i have an error on a specific action.
I compared everything i though about, the ide build is the same, but i still get an error.
I'm confused. Do you guys have an idea or a lead to follow ?

And here is the error thrown by my plugin :

Unhandled exception in [StandaloneCoroutine{Cancelling}@5592aa57, EDT]

It happens on navigation.

And the code where it is thrown : 

class OfbizCommonDocumentationProvider extends AbstractDocumentationProvider {

    static String getQuickNavigateInfo(PsiElement element, String elementName) {
        if (!element || !element instanceof XmlTag) return null
        ProjectServiceInterface structureService = element.getProject().getService(ProjectServiceInterface.class)
        return getTag(element) ? getQuickNavigateDocForElement(getTag(element), structureService, elementName) : null
    }

    static String generateDoc(PsiElement element, String elementName) {
        if (!element instanceof XmlTag) return null
        ProjectServiceInterface structureService = element.getProject().getService(ProjectServiceInterface.class)
        XmlTag tag = getTag(element)
        if (!elementName || !tag) return null
        switch (tag.getLocalName()) {
            case 'service':
