When I try to open keyboard shortcuts with Window . preferences - General - Keys it shows error: "Invalid thread access" .

Eclipse IDE for Enterprise Java and Web Developers (includes Incubating components)
Version: 2021-03 (4.19.0)
Build id: 20210312-0638
OS: Windows 10, v.10.0, x86_64 / win32
Java version: 11.0.5

Is there a possible fix for this issue?

Thank you!

no, I have not, this release is what we use standard.
Actually I think it was working after setting up Eclipse, but the problem appeard after I installed a language pack.

If it helps I found this stack trace in the problems tab:
