This might be a configuration issue. The act warnings are handled by the wrappers brought by @testing-library/react.

Please try to remove unnecessary calls and config entries like
https://github.com/KevinEonix/DevExpressVitestError/blob/13404333f4fc9aa8d5935520a9ae4fea98a033e9/src/FormForTest/FormForTest.test.tsx#L6-L8
https://github.com/KevinEonix/DevExpressVitestError/blob/13404333f4fc9aa8d5935520a9ae4fea98a033e9/vite.config.ts#L32

If the problem persists, please try to reduce the reproduction to a minimal example that still displays the issue – preferably without third-party libraries like react-hook-forms.

I tried without the configs and the cleanup call but unfortunately, i have the same issue.
