help, mcreator doesn´t want to work for me, please help

I stopped using mcreator for a few months and when I use it again today it loads the normal start but then it goes blank, everything remains blank but it is only mcreator, I looked for the problem and it tells me that it is incompatible, I have version 2021.2, it makes no sense to tell me that it is incompatible, someone has any idea what happens to my mcreator?
