I confirmed that this does happen on non-reorg as well (happens with v2.10.2).

The patched method looks like this:

The patch which is failing is simply returning the same instructions:

[HarmonyPatch(typeof(MainMenuViewController), nameof(MainMenuViewController.HandleMenuButton)]
internal class Patch
{
    [HarmonyReversePatch]
    private static void ReversePatch(MainMenuViewController.MenuButton menuButton)
    {
        throw new NotImplementedException("Reverse patch has not been executed.");

        IEnumerable<CodeInstruction> Transpiler(IEnumerable<CodeInstruction> instructions)
        {
            return instructions;
        }
    }
}
