Tests failing when run in parallel

[dmint789]

I'm having an issue with my tests only working when run individually, but not when run together. I have a setup with RTL, Vitest and MSW. When I run a test it works correctly, but when I run a suite with multiple tests, the components get stuck in the loading state, even though I can see that MSW is returning the requested data and the component is receiving it. I should mention I'm on React 19 with Next JS.

I know there are groups for receiving support, but from what I can tell they're not very active (at least based on the Discord).

I'm also facing the same issue while upgrading the React version from 19.0.0 to 19.1.0.

I have the same issue on React 19 too
