MCreator Problem export any mod (build faild)

hello I have a problem, I have been trying to export my mod for some time but there is a problem when I try to save or edit it show me "Build failed" no mod element is damaged because no new mod wants to save. I tried uninstalling and reinstalling in .exe and .zip but always the same effect. I deleted all files related to Java and MCreator. The problem started with buying a new pc pad, but it's not his fault. if anyone knows how to help I will be grateful.

and I see this:
