Error when previewing new delimited file

[Anonymous]

Hi all,

I've recently installed Talend osdi 7.3.1 and whenever I try to add a new delimited file I get following error in the "output" preview:

Error Message: The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

Preview error. Some settings must be changed.

Note: Preview errors are generally due to a wrong encoding setting.

org.talend.designer.runprocess.shadow.ShadowFilePreview.preview(ShadowFilePreview.java:90)

org.talend.metadata.managment.ui.utils.ShadowProcessHelper.getCsvArray(ShadowProcessHelper.java:383)

org.talend.repository.ui.wizards.metadata.connection.files.delimited.DelimitedFileStep2Form$PreviewProcessor.nonUIProcessInThread(DelimitedFileStep2Form.java:1300)

org.talend.commons.ui.swt.thread.SWTUIThreadProcessor$1.run(SWTUIThreadProcessor.java:74)

I've got the latest Java version, latest Talend version and am working on a Macbook with macOS Catalina version 10.15.5.

Has anybody got any idea on how to resolve this issue?

Many thanks
