I have two bugs

Code and error, compile, or run logs belong on a paste service such as Pastebin, Hastebin, or similar, if it is longer than a few 10 lines. Code and logs should in no case be posted as a screenshot as this makes the log hard to read and parse.

Try to delete the entire <your user home folder>/.mcreator/gradle folder, create a new workspace with the same generator version as the version of the workspace failing, after the setup of this new workspace is done, open your current workspace, and click Build & run -> Build workspace, then Build & run -> Reload gradle project and then Build & run -> Regenerate code and build.
