Let $X$ be a connected, smooth affine algebraic variety over an algebraically closed field $K$ of characteristic zero. Assume we have a finite group $G$ acting on $X$ by morphisms of $K$-schemes. Choose a closed point $p\in X$. Is there a $G$-invariant affine open $U$, such that $p\in U$ and $\Omega_{X/K}(U)$ is free over $O_{X}(U)$? Notice that, in this case, the quotient space $X/G$ is also an affine $K$-variety, and that the quotient map $\pi: X\rightarrow X/G$ is finite. Furthermore, the quotient $\pi$ is étale at a point $p\in X$ if and only if $p$ is not a fixed point of any element $g\in G$. As this locus is open in $X$, my statement holds for every point $p$ in a dense open in $X$. If $p$ is fixed by every element in $G$, then choose an affine open $U$ containing $p$, which trivializes the sheaf of Kahler differentials. Then the open $V=\cap_{g\in G}g(U)$ contains $p$ and satisfies the property. I have not been able to show that this holds for points that are fixed by a proper, non-trivial subgroup of $G$.

Notice that this statement is equivalent to showing that $\pi_{*}\Omega_{X}$ is a finite locally free sheaf over $\pi_{*}O_{X}$.
