We develop a Eclipse RCP app using the Eclipse IDE. There is a Target Platform that we use (xml below) that causes errors for me -- everybody else seems to be fine.
A pop up opens and there are hundreds or thousands of the same errors:
An internal error occurred during: "RCP Target" target definition". java.lang.IllegalArgumentException
The error log reveals the stacktrace:

What I tried so far:
%USERPROFILE%\.eclipse and %USERPROFILE\.m2I tried it in a local Hyper-V Windows 11 Dev Environment VM and it gets the same issue.
Colleagues do not have this problem. I was unable to find a fix for this online and I am honestly out of ideas. Do you have any idea what might be wrong?
As it turns out there was a wrong version number of a dependency, the team lead of the project found it later. Their dependencies were cached so it worked for some time. It is now fixed.
