I have a JavaFX application (I'm new to JavaFX) and in that application I have a WebView. There are no errors when I run the application until the webview loads the webpage. I have attempted to Google my way through the error the last three hours. I've read that the heap might not be big enough, so I allocated more memory to the VM heap. I've read that I have to specify the WebView module, which I also tried in VM arguments. I'm using IntelliJ and have no other errors in the project. The following error repeats about 10-15 times after the webpage loads in my application. No crash's, WebView appears to be functional, I just want to know why I have so many errors in my terminal when I run this application. If I need to provide anymore information please let me know, and my apologies beforehand. Using Maeven as my package manager.

Make sure you are using the same version of JavaFX for everything.
Your stack trace indicates that you are using [email protected] and javafx.web@20-ea, so different versions for the graphics core and the webview component.
Don't use early access software (ea) unless you have a specific need for it and, if you do, ensure you are using all of the compatible components required for it.
But you don't need to use early access software here, instead, use [email protected], and the same version for all other JavaFX components.
As an FYI, the ImageStorage.getInstance() method was added in this commit, for this issue, which is only applied to JavaFX versions 19+, which is why the 20ea software can try to use it but the 18.0.1 software does not supply it. If you wanted to support the feature from the issue:
JDK-8277572 ImageStorage should correctly handle MIME types for images encoded in data URIs
then use 19 as the version for all of your JavaFX dependencies.
